Series 616W Differential Pressure Transmitter

Series 636D Fixed Range Differential Pressure Transmitter

Series 608 Intrinsically Safe Differential Pressure Transmitter

Ranges Down to 0.1" w.c., FM Approved, NEMA 4X

The Dwyer® Series 608 Differential Pressure Transmitters convert positive, negative (vacuum), or differential pressures of clean, dry air or other non-conductive, non-corrosive gases into a standard two wire, 4-20 mA output signal. The use of an ultra thin silicon diaphragm enables precision measurement of differential pressures as low as 0.1" of w.c. while withstanding high static working pressures up to 100 psig (6.89 bar). The Series 608 transmitters are FM approved intrinsically safe for use in the specified hazardous locations when used with an approved intrinsic safety barrier. The rugged NEMA 4X, stainless steel housing makes this transmitter ideal for use in industrial and process plant environments.

Questions

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.
