Type 8311 pressure sensor/switch is designed especially to switch a valve, relay or pump and establish a simple ON/OFF control loop. The sensor may be used to energize a relay or provide transistor output (NPN or PNP) upon any pressure set point.

This tool has accuracy at ±1% of full scale with 0.25% repeatability. Type 8311 measures line pressure ranges up to 720 psig. It features a programmable set point which can be set locally with the three push buttons on the display, or externally from a PLC/computer over a 4-20mA loop.

Applications include control of air or fluid pressures in tanks, the monitoring of flow pressures in water treatment systems, or control of tank level via hydrostatic head. Its plastic sensor/switch body has process connections of 1/2-in. NPT fittings. Wetted surfaces can be stainless steel, PFM or EPDM. Type 8311 gives superior long-term performance of 100 million switching cycles minimum.

The unit is equipped with a large LCD display, which indicates the actual process value in real time both digitally and simultaneously as an analog bar graph for quick reference. Standard TEACH-IN and test simulation functions enable convenient setup and precise field calibration without applied pressure, saving time and cost.
