ADPT-ELP Differential Air Pressure Transmitter

Description

The Low Pressure Transmitter can be used to measure positive, negative or differential pressure in the ranges of 1”wc to 20”wc. The highly accurate piezoresistive sensor is ideal for monitoring pressure of non-corrosive, non-ionic working fluids such as clean dry air or other inert gases. It features field selectable pressure ranges and output signal types for the most flexible application. Typical HVAC applications include monitoring of filter differential pressure or clean room pressure. The output signal is factory calibrated and temperature compensated for highest startup accuracy and trouble-free operation.

NOTE: Please specify model/range required on any order (from datasheet)
