Disadvantages: high output impedance, low load capacityYLE Crank Position Sensors

Capacitance weighing 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 YLE Engine Temperature Sensors 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: output characteristics of nonlinearThe output characteristic of capacitance weighing sensor is nonlinear, although the use of differential type to improve, but YLE Camshaft Positioning Sensorcan not be completely eliminated. Capacitance 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.

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.

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 .
