Dwyer Series 608

Series 608 Intrinsically Safe Differential Pressure Transmitter

Dwyer Series 608
Series 608

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.
