4-20mA Low Cost Oil Pressure Sensor For Auto
WNK80mA can be used in automotive air conditioning systems. Continuous pressure signal is input to the ECU, so that the ECU controls the power of the car air-conditioning compressor, and avoids setting the pressure in the system too high or too low, to ensure that the air-conditioning system is always in a safe working pressure range, and the temperature and humidity are comfortable to humans.
WNK80mA adopts ceramic capacitor core, which has high stability and high precision. With stainless steel casing, it is flame-resistant, oil-resistant and chemical-resistant, and can work in a variety of environments.
Selection of pressure sensor
> Confirm the type of measurement pressure
WNK80mA is ceramic pressure sensor,it can measure gauge pressure and negative pressure(-50kPa)
> Check the range of the pressure sensor
WNK80mA can provide range from 3bar to 150bar gauge.
> Check the measuring medium of the pressure sensor
Some measurement media will have characteristics such as permeability and corrosiveness, which will affect and destroy the pressure sensor. Therefore, it is necessary to consider its tightness and corrosion resistance when selecting the sensor.
> Check the accuracy of the pressure sensor
WNK80mA provide 0.5%-1% accuracy
> Check the applicable temperature range of the pressure sensor
WNK80mA operate temperature -20~85℃
