GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM ULTRA LOW PRESSURE TRANSMITTER EUP SERIES PRODUCT DESCRIPTION The EUP can be used to measure positive, negative or differential pressure in the ranges of 25 Pa to 100 Pa and 0.1”wc to 0.4”wc. The pressure sensor technology is based on thermal flow measurement of gas through a micro-flow channel within the sensor chip, which results in superior sensitivity for ultra low pressures. The device features field selectable current or voltage output signal types and can be set for unidirectional or bidirectional pressure measurements for the most flexible application. The output signal is factory calibrated and temperature compensated for highest start-up accuracy and trouble-free operation. Typical HVAC applications include monitoring of filter differential, room or building pressure. The EUP is housed in a polycarbonate enclosure with a hinged and gasketed cover for ease of installation. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. The EUP mounts on any surface using the two holes provided on the base of the unit. Make sure there is enough space around the unit to connect the pressure tubing without kinking and avoid locations where severe vibrations or excessive moisture are present. The enclosure provides mounting tabs for ease of installation. ACCURACY ±1% F.S.O.
