Vacuum Pressure Sensor

The vacuum pressure sensor is used to monitor the relative pressure in the vacuum booster.

Feature and benefits

VBS can provide a signal

Internal relative pressure signal of vacuum brake booster after pressure sensing element and chip processing

Performance and customer interface compatible with Bosch TMAP

Single chip solution ,SMT for EMA fabrication process

Use waterproof and breathable film to prevent dust and moisture from entering

Different pressure ranges are available on customer request

Application

The vacuum pressure sensor detects the pressure value of the vehicle vacuum booster and outputs it to the start stop system.

Operate
Basic principle

The vacuum pressure sensor detects the pressure value of the vehicle vacuum booster through the pressure difference, that is, the pressure difference between atmospheric pressure and vacuum booster, converts the pressure into an electrical signal and outputs it to the start stop system, so as to save energy.

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.
