Quick Overview

The PS series switches are a cost effective solution for various applications in building automation systems in the HVAC/R industry. The PS series sensor include a field adjustable dial with switching ranges from 20-200 pascals up to 500-4500 pascals and maximum pressure of 50kPa. Switching contacts are rates to 3 amps @ 250vAC, allowing the switch to be used for alarming, or to operate fan motors to maintain pressure or flow ranges. The PS switch is a simple mechanical differential pressure switch which can be used for fan, blower and filter monitoring, clean room pressure monitoring, or valve and damper monitoring.
