Servoflo Corporation Low Differential Pressure Transmitter AI179

DESCRIPTION Model 179 Series are low-range differential pressure transmitters. Each unit features a push-activated pressure equalization button, two Zero push button switches, a LCD and two LED lamps. With our unique push-activated pressure equalization button, the zero calibration can be performed without disconnecting the pressure tubes. It significantly reduces time and cost for users. The AI179 has a stainless steel front panel and a stainless steel back enclosure. The pressure ranges from 20 Pa to 20Kpa, unidirectional or bidirectional. The output is 2-wire 4-20 mA, fully protected against short circuiting and incorrect wiring. All units are temperature-compensa ted with available accuracies of 0.8%, 0.4% and 0.25% FS. The patented stainless steel diaphragm sensor provides good corrosion resistance, excellent repeatability and long term stability. FEATURES 3 1/2 digit LDC display Up to 15 PSI overpressure Incorrect wiring protection SS304 flush mounting RoHS Compliance Pressure ranges as low as 10 Pa Temperature-compensa ted Uni-directional or bi-directional TYPICAL USES HVAC air pressure and VAV pressure sensor Cleanroom pressure and fume hood airflow control Duct static pressure measurement Draft control Furnace airflow control Isolation rooms
