Low Range Differential Air Pressure Sensors

The DPT-R8 is an electronic differential pressure transmitter with eight jumper selectable measurement ranges in one device, from +/-100PA up to 0-7000Pa. The output is selectable as 4-20mA or 0-10V. The units also have the option of an LCD or Auto Zero function.

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.
