Barksdale BPS31NVM0150P Electronic Pressure Switch 150 Psi

Product Description

The BARKSDALE BPS31NVM0150P is an electronic pressure switch with an integrated digital display, designed for use in industrial and commercial fluid system monitoring applications. Rated to 150 psi maximum, it delivers 0.5% accuracy and outputs a PNP switch signal through an M12 connector. The 1/4 inch NPT male process connection threads directly into standard pressure ports. The unit operates across a temperature range of -13 to 212 degrees F and is rated at 32 volts. It is installed by industrial technicians, HVAC mechanics, and fluid system service professionals requiring precise, configurable pressure switching with a readable on-device display.

This pressure switch is suited for hydraulic, pneumatic, and process fluid applications where a reliable setpoint switch output and local pressure readout are required. The PNP output signal is compatible with PLC inputs and control panels common in commercial HVAC, building automation, and light industrial systems. The compact housing and standard 1/4 inch NPT male fitting make it straightforward to integrate into existing pressure monitoring circuits without adapters in most setups.

Compatibility

Designed as an OEM-style replacement or new-installation electronic pressure switch for industrial, commercial HVAC, and process fluid systems using 1/4 inch NPT male pressure ports and PNP control inputs.

Installation Notes

Installation should be performed by a qualified technician familiar with the applicable fluid system and electrical codes. De-energize the control circuit and depressurize and isolate the system before removing or installing this switch. Use appropriate thread sealant on the NPT connection and do not overtighten, as this may damage the wetted port or sensor element. Verify that the supply voltage and PLC input type are compatible before commissioning.
