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.
