PDIGR-LP2 Series Low Pressure Transducers

Overview

The PDIGR-LP2 Series are low pressure transducers. These devices can be used to measure positive, negative or differential pressure in the ranges of 1”W.C. to 12”W.C. (200 to 2000Pa). The piezoresistive sensor is ideal for monitoring the pressure of air or other clean inert gases and is limited only to those media which will not attack polyetherimide, silicon, fluorosilicone, silicone, EPDM and neoprene seals.

The PDIGR-LP2 Series features field selectable pressure ranges and output signal types for the most flexible applications. The output signal is factory calibrated and temperature compensated for highest startup accuracy and trouble-free operation. Available options include LCDs and integrated static pressure probes.

This product offers a cost effective solution for customers who wish to have ease of installation to their Building Automation System.
