Model 178A Front Panel Mounting Differential Pressure Transmitter
The model 178A Series pressure monitors are low-range differential pressure transmitters. Each unit features a push-activated ZERO function and an associated LCD display. With a convenient push button, the zero calibration can be performed without any additional equipment. It significantly reduces time and cost for users.
The 178A series pressure differential monitor has a SS304 front panel and an IP65/NEMA 4 rated aluminum die casting enclosure to withstand environmental effects. The pressure ranges from 0.1″WC to 100″WC, unidirectional or bidirectional. The output is 2-wire 4 to 20mA, fully protected against short circuiting and incorrect wiring.
All units are temperature compensated. 0.6%, 0.4% and 0.25% accuracies are available. The patented stainless steel diaphragm sensor provides good corrosion resistance,excellent repeatability and long term stability.
