Excellent overpressure capability with a maximum overpressure of 28 bar.
User-defined fixed pressure setting with tamper-proof housing.
Available in a broad range of mounting threads.
Withstands acceleration up to 4G, suitable for tough applications.

Application
The DSP Pressure Switch is ideal for applications where resistance to environmental elements is crucial. It is suitable for engines, pumps, compressors, gearboxes, and industrial power plants.

Physical Description
The switch features a compact, non-adjustable design with a 24 A/F hex brass body, allowing direct integration into applications. It senses pressure through a small orifice at the thread base and ensures reliable electrical connections using a Deutsch DT 2-way connector.

Operation
The DSP can trigger an alarm or initiate a shutdown at a pre-set pressure to prevent machinery damage. It has a differential of 0.15 bar and automatically resets when pressure drops.

Installation Considerations

Ensure sufficient clearance around the body flats.
Do not exceed maximum pressure for longevity.
Use genuine Deutsch DT connectors for accurate pressure measurement and protection.

Deutsch DT 2-Way Compatible Exceeds IP67 Excellent Over Pressure Capability User Defined Fixed Setting Tamper Proof Housing Broad Choice of Mounting Threads Available WithstandsAcceleration to 4G Rugged Construction for ToughApplicationsApplication Operation The DSP consists of a single compact non-adjustable unit based on a 24 A/F hex brass body.This enables the control to be fitted directly into the application. The DSP senses pressure through a small orifice at the base of the thread. Reliable electrical connection, in the toughest of conditions, is made using a Deutsch DT 2-way connector. IP67 rated, this connector is hot pressure washer resistant and is used by leading automotive manufacturers. DSP Pressure switches are ideally suited for use on all types of engines, pumps, compressors, gearboxes, industrial power plant and other applications where resistance to the elements is the primary consideration. Should a hazardous condition arise, the DSP can be arranged to operate an alarm or initiate a shutdown at a pre-determined operating pressure, preventing damage to valuable plant machinery. Physical Description Installation Considerations Check there is enough clearance around the flats of the body and ensure the maximum possible pressure is not exceeded for a long service life. The DSP has a differential of 0.15 bar and provides automatic reset upon application pressure drop. For accurate pressure measurement, reliable connection and Ingress Protection, it is essential that genuine Deutsch DT connectors be used. >
