608-00B is a series 608 intrinsically safe differential pressure transmitter which converts positive, negative (vacuum) or differential pressures of clean, dry air or other nonconductive, non-corrosive gases into a standard 2-wire, 4-20mA output signal. Use of an ultra-thin silicon diaphragm enables precision measurement of differential pressures while withstanding high static working pressures up to 100psig (6.89bar). It is FM approved intrinsically safe for use in specified hazardous locations when used with an approved intrinsic safetybarrier. High accuracy at low-pressure ranges provides an exceptional measurement for ensuring tight control and minimizing costly out-of-specification conditions. Intrinsically safe for use in specified hazardous locations meets specifications where pressure transmission and safety cannot be compromised. Typical applications include lab fume hood control, clean room applications, flow measurements and control, filter monitoring and process control.
