The weighing sensor can be said to be one of the most important parts of a electronic scale

The weighing sensor can be said to be one of the most important parts of electronic scale, weighing sensor and then is in addition to IC, mainly for the two core elements, weighing sensor is itself an analog signal, when a weight to the weighing sensor at the top, in the sensor element elastic will produce a deformation, the change changes in the load YLE Engine Water Temperature Sensor at about 1mm. When the deformation, strain is stuck on the elastic element above meter fine wire delete will bend and try for, a total of 4 sheet resistance, according to the principle of Wheatstone bridge, when the resistance strain gauge and try for the resistance to bending when the 2 directions, one is the positive direction to a negative direction, we read his numerical is this difference, the difference of different deformation, YLE Car Temperature Sensorbut this is linearly proportional to the number of, of course there are some small error. This error because of the location and the material is affected, it is called nonlinear. So when a platform balance before we all need calibration and calibration, considered from the 2 aspects, one is the output, one is nonlinear. This is the primary output of strain gauge, the output signal is very weak, the normal condition, so the IC to the signal processing, allows the user to read to understand Kg and pound figure.

What is the characteristics of strain pressure sensor

Pressure sensor is a kind of commonly used sensors, widely used in medical, ships, aerospace, petrochemical, machine tools and other industries. Pressure sensors need to know when in use of knowledge is also a lot of, among them the characteristics of strain pressure sensor for users is also a need to understand, here is for everyone to introduce what is the characteristics of strain pressure Automobile Temperature Sensor.The measuring range of the pressure sensor is twice as big as the inductive sensor, it can not only detect metal target, but also detect dielectric, such as paper, glass, wood and plastics, and even can be detected by a wall or paper shell. Because the human body in low frequency is equal to the electrical conductor, thus can be used for the quiver measurement and alarm.
In the measurement of strain, the strain gauges can be on the component, but if the measuring force, pressure, acceleration, should first change the physical quantity measuring strain, and strain gage, a conversion process more than direct measurement, to complete the conversion process is usually called the original as the elastic elements, therefore, the strain Camshaft Position Sensor is usually made of elastic sensitive components and the strain gauge is composed of two parts.
Elastic sensitive element is a core component of sensor, elastic component of elastic energy storage requirements high, usually expressed as elastic material storage and deformation work without permanent deformation. Pressure sensor has good mechanical processing and heat treatment performance, has high compressive strength.

The structure and working principle of the knock sensor

Knock sensor is an important component of engine electronic control system, its function is to detect whether the engine detonation, and the signal sent to ECU engine. Knock sensor common has two kinds, one is the magnetostrictive knock sensor, a piezoelectric type knock sensor. Magnetostriction type knock Engine Water Temperature Sensor in which a permanent magnet, permanent magnet excitation by around the magnetic core and the iron core coil.

Capacitance weighing sensor's faults

No matter what the sensor has its own advantages and disadvantages, the weighing sensor is the same, it is mainly used to quality signals into electrical signals, the advantages of capacitance sensor is low power consumption, low cost, what are the disadvantages of it, we come to understand in detail. Disadvantages: high output impedance, low load capacity
Capacitance Cooling Temperature Sensor capacity by the electrode geometry restriction very difficult to do, generally tens to hundreds of micro method, even only a few micro method. Therefore, the output impedance capacitive weighing sensor is high, so the load capacity is poor, vulnerable to outside interference produced unstable phenomenon, serious and even unable to work. We must take shielding measures properly, to design and the use of inconvenience. Capacitance sensor also requires insulation resistance value is extremely high, otherwise the insulation performance of part as bypass resistance and affect the instrument, so we should also pay special attention to the surrounding environment such as temperature, cleanliness, etc.. If the use of high frequency power supply, can reduce the output capacitance weighing sensor resistance, but the high frequency amplifier, sensor than low frequency complex, and the effect of parasitic capacitance, is not easy to ensure the stability of the work. Two shortcomings: the output characteristics of output characteristics of nonlinear capacitance weighing sensor is nonlinear, although the use of differential type to improve, but can not be completely eliminated.Engine Coolant Temperature Sensor for other types of only ignores the edge effect of electric field, the output characteristics is linear. Additional capacitance or the edge effect will be directly superimposed sensor capacitor, the output characteristics of nonlinear. Disadvantages: three parasitic capacitance effect of initial capacitor capacitance weighing sensor is small, and the lead capacitance, electronic circuit connected with the sensor and the electronic circuit of the stray capacitance and inside Coolant Temperature Sensor plate and the surrounding conductors capacitors and other so-called missing large parasitic capacitance, not only reduces the sensitivity of the sensor, and the capacitance is often random variation the instrument, work is not stable, influence the accuracy of measurement. So the cable selection, installation, connection method has strict requirements. For example, with good shielding property, its small distributed capacitance of high frequency electric wire as the lead, lead is thick and short, to ensure the instrument stray capacitance is small and stable and so on, otherwise it can not guarantee the high measurement precision. It should be pointed out that, along with the material, technology, electronic technology, especially the rapid development of technology, the capacitance weighing sensor has been developing and constantly overcome shortcomings. The capacitance sensor is becoming a high sensitivity, high precision, low pressure sensor in dynamic, and some special measurement has a promising.

These sensors have their own economic and technical characteristics. Therefore, consumers should be generous to accept their presence , so you can successfully promote the great advances in technology . However, the new sensors are not necessarily mature technology , a lot of new products out of the technology was not mature enough , but not to promote technological progress, so that either improve them or let them social outcasts . Some flow sensor is not sufficient in many occasion in experiments conducted in the laboratory, but only some of the experiments on the market . In fact, these sensors , there are still many unknown factors, but does not have the national conditions of some of the technical regulations .

Sensor problems generally are the following

In the pressure sensor maintenance work , through integration of data and found that the sensor problems generally are the following : 1 , base, and a lot of oil around the plate four weeks , thus causing the insulation effect is not ideal. 2 , the gap between the base plate and the other end of the small end large, this is because the sensor base of the following mill base circle , which has been subject to the impact of the role of the rolling force , no longer meet the installation requirements , when the level of the . 3 , after the sensor is removed , the same position that it has the appearance of a very severe wear , some have even been corrosion , so the force is no longer uniform . 4 , the west under the indenter roll the extent of damage severe than the east , the number was significantly higher , analyze the results that may be mill drive west end , so by rolling impact will be higher than the big east .
Respond to some of the problems above we generally there are several solutions. 1, from the rolling mill stand removed at Crankshaft Positioning Sensor base , and then measure the surface and the lower surface of the base circle , the horizontal and flatness must be measured. 2 , the lower plate below the increase in skin thickness of 0.6mm copper because of its good ductility , a level sensor is installed can have a certain compensation. The pressure test data show that the new added to the copper plate at certain positions of the indentation has one millimeter thick , and some of them have almost been pressed to wear , this description is not enough to force uniform . 3 , removeCoolant Temperature Sensor after the sensor , both the upper and lower plate and pad roughness , flatness , parallelism and geometry measurements , generally can be found in both the upper and lower platen plate precision installation requirements have been much lower than the . Only learn how to maintain mill pressure sensors, in order to make better use of rolling pressure sensor , the only way to make life more permanent , better service.

Non-contact temperature sensor sensitive components in contact with the measured object and do not

Non-contact temperature sensor sensitive components in contact with the measured object and do not , also known as non- contact Thermometer . This Automotive Temperature Sensors is used to measure moving objects instrumentation , small target and heat capacity smaller or rapid temperature changes ( transient ) the surface temperature of the object , can also be used to measure the temperature of the temperature distribution . The most commonly used non- contact Thermometer Based on the basic law of blackbody radiation , called radiation thermometer tables. Including brightness radiation thermometry method ( see optical pyrometer ) , radiation ( see radiation pyrometer ) and colorimetry ( see colorimetric thermometer ) . Various types of radiation thermometry method can only measure the temperature corresponding to the luminosity , temperature or radiation colorimetric temperature . Only blackbody ( absorbs all radiation is not reflected light of the object ) is the real temperature of the measured temperature . To determine the true temperature of an object , it must be material surface emissivity correction . The emissivity of the material surface depends not only on temperature and wavelength , but also with the surface state , and microstructure of the coating , etc., and therefore difficult to accurately measure . In automated production method often requires the use of radiation to measure the temperature or the surface temperature control some , such as metallurgical rolling temperature of the strip , the roll temperature, the forging temperature, and a variety of molten metal in the smelting furnace or a temperature in the crucible . In these particular cases , surface emissivity measurement is rather difficult . For solid surface temperature automatic measurement and control, the use of additional mirror surface with the composition of the measured blackbody cavity . Additional effects of radiation can increase the effective surface to be measured and the effective radiated emission coefficient . By using effective instrument for emission coefficient measured temperature corrected accordingly , and ultimately obtain the true temperature of the measured surface . The most typical auxiliary reflector is hemispherical reflector . Coolant Temperature Sensor the center of the sphere diffuse radiation reflected back by the mirror surface of the hemispherical form additional radiation, thus increasing the effective emission coefficient of the formula: wherein ε is the emissivity material , ρ is the mirror reflectivity. As to the gas and the liquid medium to the real temperature radiation measurements, the heat-resistant material can be inserted into the tube to a certain depth to form a blackbody cavity approach. Obtained by calculation to reach thermal equilibrium with the medium after the effective emission coefficient cylindrical cavity . In the automatic measurement and control can use this value for the measured temperature at the bottom chamber ( ie, medium temperature ) is corrected to obtain the true temperature of the media .

If the temperature T1 of the thermal resistance at temperature T2 into the medium , provided the thermal resistance in contact with the medium surface area A, the thermal resistance of the heat dissipation Q can be expressed in: Q = KA (T1-T2), formula , K is the thermal conductivity , or heat transfer coefficient . Experiments show that , K and medium density , viscosity, average flow rate parameters. When other parameters are constant , K- only medium is proportional to the average velocity . By measuring the thermal resistance of the heat dissipation Q can be measured the average velocity or flow medium . Thermistor sensor has a small size, fast response, high sensitivity , so it is widely used in many fields . Camshaft Position Sensor in industrial applications is very wide, depending on the product model, its scope is also not the same line , specifically the following aspects: Thermistor Temperature : As a thermistor temperature measurement sensors are generally relatively simple structure , the price cheaper . No outside protective layer thermistor can only be applied in a dry place ; sealed thermistor afraid of moisture erosion, can be used in a relatively harsh environment . Since the resistance of the thermistor sensor is large, so the connecting wires and the contact resistance of the resistance can be ignored , so Engine Coolant Temperature Sensor at the temperature up to several kilometers of distance measurement applications, multi-use bridge measurement circuit . The principle can also be used as the use of other temperature measurement and control circuit. Thermistor for temperature compensation of the sensor : ThermistorShaft Position Sensor in a certain range to compensate for certain components humidity . For example, moving coil meter moving coil header by the copper wire around the system . Temperature increases , the resistance increases, causing the temperature errors. And can therefore be of the moving coil circuit will be negative temperature coefficient thermistor manganese copper and then with the resistor in parallel with the series compensation components , in which to offset the error caused by temperature changes . In the transistor circuit , logarithmic amplifier , it is also composed of a thermistor compensation circuit used . Compensation due to temperature drift errors . Thermistor sensor overheat protection: thermal protection of direct indirect protection to protect profits . The small current case, the thermistor sensor can directly load string person , to protect the device to prevent overheating damage , for large current applications , can be used for the relay , transistor circuit protection. In either case, the thermal resistance of the device to be protected are close together , so that heat exchange between the full , the event of overheating , the protective effect of the thermistor . For example , the stator winding of the motor thermistor embedded in the mutant and in series with the relay . When the motor is overloaded, the stator current increases , causing fever . When the temperature is higher than point mutations , the current in the circuit can be within a few tens of milliamperes is mutated to tens of milliamps , the relay, in order to achieve thermal protection. Thermistor sensor for liquid level measurement : NTC thermistor sensor to put some heating current , its surface temperature will be higher than the surrounding air temperature, at which point it 's less resistance . When the liquid and higher than its installation height, it would take away the heat of the liquid , so the temperature drops , the resistance increased. Determine its resistance changes , you can know whether the liquid level is below the set value . Oil level in the tank car Automotive Temperature Sensors is produced using the above principle . Thermistor in the car is also used to measure the oil , the cooling water mixed with other .

The compound of the resonator and the vibrator consists of a metal plate and a piezoelectric ceramic bimorph element consisting of a combination of the vibrator . Resonator flared aims to effectively radiate ultrasonic waves generated due to vibration , and the ultrasonic waves can be effectively central portion of the vibrator . Piezoelectric ceramic ultrasonic sensor uses a point to note is that in the high- frequency probe , you must use the vertical thickness vibration mode piezoelectric ceramic . In this case , the acoustic impedance of piezoelectric ceramic matches with the air becomes very important . Because the acoustic impedance of the piezoelectric ceramic 105 acoustic impedance of air , which will cause the vibration of the piezoelectric ceramic significant loss of radiation on the surface , then you will need to adhere to a special material on the piezoelectric ceramic Crankshaft Positioning Sensor , as acoustic matching layer , the air can be realized with acoustic impedance matched , so as to achieve the purpose of the measurement .

Metal resistance strain gauges have filamentous strain gauge and the metal foil strain gages two kinds . The strain gauge is usually via a special adhesive binder tight mechanical strain is generated on the substrate , the force occurs when the substrate stress , the resistance strain gauge is generated with deformation, the resistance strain gauge is changed , so that the the voltage across the resistor changes . The strain gauge force generated when the change in resistance is usually small , it typically are composed of strain gage bridge , and through subsequent instrumentation amplifier is amplified , and then transmitted to the processing circuit . Strain gauge Crank Position Sensoris generally shock and impact resistance is better, but this sensor accuracy with their manufacturers . The second method is to use an ordinary ceramic Shaft Position Sensor or pressure sensor to measure diffusion silicon , but not be measured directly , but with the addition of a buffer tube , which also can measure the impact pressure . This method is economical , easy to install , so the application is very extensive. Regardless of the method is to measure the impact pressure sensor core body protection is not strong pressure washed out . Which method based on the specific use now have a bad environment and customer choice .

It is by conduction or convection and thermal equilibrium state , it can be directly displayed value represents the case of the measured temperature of the object . Generally, it 's measurement accuracy is relatively high . Within a certain temperature , it is even able to measure the temperature inside the object of each case . However, if the measurement is the movement of objects , the heat capacity of small objects or small target, the measurement results will have a relatively large errors , frequent use of the thermometer with pressure thermometer , resistance thermometers , bimetal thermometers and glass liquid thermometers, etc.Crankshaft Positioning Sensor. They are in the commercial, agricultural and industrial applications are very wide , even in normal life , people often use these thermometers. In electronics, medicine, metallurgy , defense engineering and food sectors , cryogenic technology is widely applied , and there are strong research on superconducting technology , and now you want to measure the temperature of the low temperature below 120K thermometer has been well development , such as : acoustic thermometer, temperature heat thermometer , vapor pressure thermometer, gas thermometer and temperature and so on.
