608-02 608-03 608-04/05/06/07/10B/13B/04B Dwyer德威尔 微差压变送器

The Dwyer SERIES 608 Differential Pressure Transmitters convert positive, negative

(vacuum), or differential pressures of clean, dry air or other non-conductive, noncorrosive

gases into a standard two wire, 4-20 mA output signal. The use of an ultrathin

silicon diaphragm enables precision measurement of differential pressures as low

as 0.1 in 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.

FEATURES/BENEFITS

? High accuracy at low pressure ranges provides exceptional measurement for

ensuring tight-control and minimizing costly out of specification conditions

? Intrinsically safe for use in the specified hazardous locations meets specifications

where pressure transmission and safety cannot be compromised

? NEMA 4X rated enclosure provides protection in harsh environments permitting

outdoor monitoring or in areas where dust and particulate matter exists
