Product Details
  • Sub Category:Sensor
  • IMPA/Product Code:--

The polysilicon varistor designed by the company is used as the signal acquisition source of the transmitter, and the signal processing is carried out by using the high-temperature-resistant imported ASIC. A linear current signal proportional to the pressure is obtained.

main feature:

  1. The ASIC handles the output signal of the sensor, and the working temperature can reach -30 ° C ~ 120 ° C;

  2. The self-designed compensation program performs linear calibration and temperature compensation, and the work is stable and reliable;

  3. Can be used in a variety of media;

The main purpose:

  1. Vehicle stability control;

  2. GDI fuel pressure;

  3. Gearbox

  4. Seat bearing sensing measurement;
