Differential pressure switch

The differential pressure switch is an important sensor in the vehicle system and serves to monitor the pressure difference between two points in a system. It is frequently used in various vehicle components, for example in the exhaust system, in filter systems, or in pneumatic and hydraulic systems.

The differential pressure switch measures the pressure before and after a specific component, such as a filter or valve. If the pressure difference reaches or exceeds a defined limit, the switch triggers an electrical signal. This signal is transmitted to the vehicle's control unit and can trigger certain functions or activate a warning message.

A common application is the monitoring of particulate filters or air filtration systems, where an increased differential pressure can indicate a possible blockage or increased flow resistance. The differential pressure switch can also be used for system monitoring in hydraulic or pneumatic systems.

The components consist of precision sensor elements, electrical contacts, and robust housings protected against moisture, dirt, and temperature fluctuations. This ensures reliable pressure measurement and signal transmission.
