Oxygen YLE Camshaft Position Sensor link metal often provide free electrons. The ceramic insulator is generally excellent ? . But only in theory , as the temperature approaches absolute zero , ceramic thermistor is such a case . However, when the temperature increases to more common range, thermal excitation will throw more free electrons. With many carriers through electronic ceramics, effective resistance is reduced. Resistance changes with temperature is extremely YLE Crankshaft Positioning Sensorsensitive. Typical variation for each degree Celsius decrease ( - ) 7 [ % ] to 3 [ % ] . Then fit a wide temperature range of any sensor used is most sensitive .

What is the working principle of the anti explosion sensor

For the use of sensors in flammable and explosive occasions, in order to avoid the occurrence of explosion, usually with explosion-proof requirements of the product. There are three main sensor explosion-proof methods, respectively, is to control the explosive gas explosion detonated, control limitations and control source. The working principle of the three methods do briefly introduce: 1, control and explosive gasThe working principle is the box body burst in a sealed compartment, with clean air or inert gas does not contain explosive gases, and keep the inside pressure is slightly higher than the tank pressure, the sensor is installed in the box. Representative for the positive pressure explosion-proof method Exp. 2, control the explosion limitThe working principle is according to Exd standard, Crank Position Sensors housing design for flameproof standard housing, according to the shell explosion-proof standard instrument design, according to the standard design, manufacture and assembly of severely all management process, in the attack the shell explosion not to excite the shell of gas explosion risk.
Isolation design and manufacture standard proof explosion-proof measures extremely severe, and operating procedures, and repair of the assembly connection is also very strict. Electrical equipment, the way of determining the flameproof instrument are very strict, the operation must be off, but many cases is the most useful method. 3, ignition control source principle is applied safety gate isolation wiring, processing from Cooling Temp Sensor is in electric power distribution, will supply the field sensor energy limited in both cannot occur enough to detonate the spark, and can safely confined to surface temperature rise within the instrument. According to the national standards of international norms and China, when the peace gate safe area at one side of the connecting device to attack any obstacle, essence safety explosion-proof measures to ensure that explosion risk on site safety need to remind you to consider in the purchase of Cooling Temperature Sensor for the use of different occasions and configuration, choose according to need the intrinsically safe type, flameproof type sensors and instrumentation also required, Ex explosion-proof certification from suppliers.

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.

Pressure sensor is how negative

Pressure sensor vacuum is how ? Pressure sensor is used to measure the negative pressure and vacuum , regular contact with the negative pressure of the pressure sensor will find generally negative pressure sensor measuring the negative pressure of the maximum range is -100kpa or is -0.1 MPA. But there are very few manufacturers say can be measured to -300kpa even lower, which in the end is how it happened ? Fact, this is two different angles analysis . Studied physics knows vacuum pressure -100kpa, so that the general Camshaft Positioning Sensor measures the pressure is the lowest -100kpa is the basis of this , so the market is basically the lowest negative Auto Temperature Sensor can measure -100kap, that - 300kpa sensor is how it happened ?-300kpa fact not refer to atmospheric pressure , and physical stress on both a reference, you can understand , in a sealed box filled 300kpa high pressure gas , which sets stood a vacuum boxes , we use negative Crankshaft Positioning Sensor placed outside the big box to measure the pressure inside a small box , which would show a -300kpa, so that -300kpa pressure is produced . It is not with reference to atmospheric pressure . Understand this concept we chose negative pressure sensor can be helpful, so we do not choose the wrong pressure sensor , which is why we often help customers choose the pressure sensor when the first use of the environment will ask him to ask his range how much. Only then will not choose the wrong pressure sensor.

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 .

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 .
