Model 178 LCD Display Differential Pressure Transmitter
The Model 178 Series variable pressure sensor 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 is with NEMA 4 (IP-65) rated
aluminum enclosures, they are very rugged and very reliable.
The Model 178 Series surface mount pressure transducer/sensor is available for
full scale pressure range from 0 to 0.1″WC till 0 to 100″WC. Both
unidirectional and bidirectional pressure ranges are offered. The output of the
Model 178 Pressure Transducer is available in two versions: 0 to 5VDC and 0 to
10VDC, where 0VDC is true zero without offset. The output of Model 178 Pressure
Transmitters is 4 to 20 mA. All units are temperature compensated. The accuracy
can be 0.6%, 0.4% or 0.25% at room temperature. Bidirectional pressure
transducer available on alphainstruments.com, feel free to contact!
The patented variable capacitance pressure sensor is constructed by stainless
steel and glass, no glue or other organics. That provides excellent
performance, corrosion resistance and long-term stability.
