Series 636D Fixed Range Differential Pressure Transmitter

Explosion-proof, 0.5% Accuracy

Series 636D Differential Pressure Transmitter can be used for measuring pressures of liquids, gases & vapors. All available ranges have an excellent 0.5% F.S. accuracy with a 4-20 mA Output standard or optional 1-5 VDC output. The NEMA 4 housing is an all 316 welded construction that is designed to withstand the harshest environmental conditions. With all 316L wetted materials, this transmitter is compatible with most media. These units are CSA approved explosion-proof for use in specified hazardous locations.

Calibration Option available under Accessories.

Question

Please advice for a differential pressure transmitter for Hydrogen

Answer

Hydrogen is a combustible gas which would need a Class I, Div I, Group B rating.You can consider the Series 608 for lower ranges or Series 636D for larger ranges.
