Single Pressure Transmitter- Series 635
Ranges from 0-20 to 0-6000 psi. Accuracy to ±1% Full Span Output.
For Higher Ranges, choose these single positive pressure models with simple, reliable Inconel® Bourdon tube pressure element. Measure and control both liquids and compatible gases with ±1% F.S. accuracy. Use as stocked or recalibrate to other spans within limits shown below. Versatile design enables use in 2, 3 or 4-wire current loops. Maximum pressure limit is 1.5 X maximum range.
