The HALP3 Series has been discontinued and has been replaced by the HALP Series.
The HALP3 High Accuracy Low Pressure Transmitter can be used to measure positive, negative or differential pressure in the ranges of 1.00” W.C. to 20” W.C. or 250 to 2000 Pa. The piezoresistive sensor is ideal for monitoring the pressure for air or other clean inert gas and is limited only to those media which will not attack polyetherimide, silicon, fluorosilicone, silicone, EPDM and neoprene seals.
The HALP3 features field selectable pressure ranges and output signal types for the most flexible applications. Typical HVAC applications include monitoring of filter differential pressure or VAV 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.
