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.

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.

Why do you want to develop a standard 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 .
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 .

The first method is to change the pressure transmitter chip , not an ordinary ceramic cores or diffused silicon core , but with strain gages , strain gauges is a strain on the DUT will be converted into an electrical signal of change sensitive device. It is a piezoresistive Cooling Temp Sensor of the main components . Resistance strain gauge is the most widely used metal resistance strain gauges and semiconductor strain gauges two kinds . 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 .
