The "76" Series measures pressures from 0 to 5" WCD to 100 PSID.High accuracy to ±0.15% FSO
Viatran's "76" Series is a small size, low range differential pressure transmitter that is extremely accurate. Measuring 3-3/4" in height and 2-1/4" in width, this unit is one of the smallest wet/wet differential pressure transmitters available.
The "76" Series measures pressures from 0 to 5" WCD to 100 PSID. To accommodate vigorous test applications, a line pressure rating of 500 PSI is standard.
Model 276 has a 0 to 5 VDC signal, and the 376 offers a 4 to 20 mA output. Viatran's capacitance sensing technology ensures long term stability and provides an accuracy of better than ±0.15% FSO.
