Oil Pressure Sensor

OPS is an important device to detect the oil pressure of the vehicle engine.

Feature and benefits

The OPS sensor provides analog signal or digital signal

With ceramic capacity technology, with both high accuracy and long-term stability. Ceramic has excellent compatibility with almost all automotive pressure media

Pressure can be customized in the range of 0~8MPa

Output with 0.5V~4.5V voltage single, with diagnosis function

Protection degree with IP69

Connector and pressure port can be customized

Application

The oil pressure sensor detects the pressure of the main oil passage of the engine oil and transmits the signal to the ECU to help control the normal operation of the engine.

When the oil pressure is lower than the expected value, the engine fault lamp and oil lamp on the instrument are always on, giving an alarm signal. The ECU will enable the protection function of reducing the engine speed and power to regulate the engine speed and power.

Operate
Basic principle

According to the change of the medium pressure in the induction pipe, the oil pressure sensor will lead to the deformation of the ceramic strain film and change the capacitance value, which will be amplified by the conditioning circuit and converted into a voltage signal.

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.
