Gasoline Direct Injection Pressure Sensor

Gasoline direct injection pressure sensor detect the pressure of direct injection pressure, for precise control of engine fuel supply.

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

Voltage output, with diagnosis function

Protection degree with IP69

Connector and pressure port can be customized

Application

Detect the pressure of direct injection pressure, for precise control of engine fuel supply.

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.

Connection options

Customized to connector and port.

Packaging Options

Custom packaging can be provided to meet customer requirement, please contact KESENS Engineering for details.
