Automotive sensor characteristics

Adaptability, resistance to harsh environments cars could travel to any area on the planet , environmental conditions vary widely , both extremely cold polar regions , there are also hot climate like the equatorial region , therefore , requires that the sensor has a strong adaptability , in a - 40 ~ 80 ℃ under the conditions Needless to adjust properly. Cars may work in extremely harsh climatic conditions , sometimes the dust filled the air, sometimes stormy , so Engine Water Temperature Sensor should have a good seal , resistant to moisture, corrosion resistance . Anti-interference ability to adapt to the external sensor in addition to the harsh environment , but also on the internal able to resist all kinds of interference from the engine . Sensors are installed in the engine compartment , in addition to the engine work to withstand high temperatures and pressures , the combustion exhaust gas corrosion , but also requires a good seismic performance, strong resistance to vibration during engine operation , in addition, the engine work will produce electromagnetic waves, thus requiring sensors with anti-jamming capability. Car power ( generators, batteries , etc. ) 6 ~ 16V voltage can change, sometimes even more than 100V superposition of negative high voltage pulse , so also with anti- surge capability. High stability and reliability of various automotive parts generally require more than capable of running 10 × 104km and goes without replacement and adjustment of the technical specifications are still met . Therefore,Car Temperature Sensor must have high stability and high reliability. Inexpensive, adapt to mass production which requires consistency of the sensor is good, no complex adjustment, for automated production.
