Cylinder Pressure Sensor

A CPS allows one to get combustion feedback from inside the cylinder, and send the signal to ECU.

Feature and benefits

Robust and reliable piezoresistive Micro Strain Gauge technology

Pressure can be customized in the range of 0~20MPa.

Excellent compatibility of operation media

Output can be SENT and Analog, with diagnosis function

Temperature Compensation is available

Protection degree with IP69

Connector and pressure port can be customized

Application

A CPS allows one to get combustion feedback from inside the cylinder, to fulfill the regulatory requirements.

Operate
Basic principle

With glass micro-melting process, piezoresistive micro strain gauge will be sintered on stainless steel port. When the pressure affected on the stainless port, silicon strain gauge will also be deformed, then its resistance value will change against the deformation. After conditioning, the resistance value will be converted into analog signal or SENT signal as needed.

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.
