EVAP Pressure Sensor

Fuel vapor pressure sensor is a kind of pressure sensor based on MEMS technology to detect the pressure in the vapor pipe system.

Feature and benefits

The working temperature range is wide, from - 40 ℃ to 130 ℃, with full temperature compensation.

High precision relative pressure sensor can detect minimal leakage in the system.

With broken line detection, output alarm function.

Appearance and customer interface can be compatible with major tire 1 suppliers’  products.

SMT for EMA fabrication process.

According to customer requirements, a variety of ranges can be customized.

Product Application

EVAP Pressure sensor is used to measure the pressure in the fuel evaporation system to help reduce gas leakage to the atmosphere.

Operate
Basic Principle

The pressure sensitive unit of EVAP sensor is affected by pressure, which leads to the change of resistance value of Wheatstone bridge, which is converted into voltage signal. The signal is amplified and compensated by signal conditioning circuit to obtain proportional voltage output. The voltage output is proportional to the pressure difference between evaporation system and surrounding atmospheric pressure and it was used to detect leakage in evaporation system.
