Purging Line Pressure Sensor

The purging line pressure sensor is used to detect the pressure of the desorption path, And convert it into an electrical signal to open the valve in time.

Feature and benefits

Intake manifold absolute pressure output /Derived from a MEMs based sensing element

Performance and customer interface compatible with Bosch TMAP

Single chip solution ,SMT for EMA fabrication process

Steel ball for vent hole sealing, laser marking for better traceability

Different pressure ranges are available on customer request

Application

With information of fuel pressure sensor, ECU can obtain information to timely open the valve, so that the activated carbon canister in the saturated adsorption state can regain the adsorption capacity.

Operate
Basic principle

The purging line pressure sensor converts the pressure change of the sensing desorption path into a voltage signal from the change of the internal resistance of the sensor, so that the ECU can get information to open the valve in time.

Connection options

Customized to customer choice of connection system.

Packaging Options

Custom packaging can be provided to meet any need, please contact KESENS Engineering for details.
