The Meriam Bellows D/Pline of instruments serves as a compliment to the
Meriam Manometers by offering a choice when pressure rating, space,
process compatibility and many other specifications are a factor. The
Meriam Bellows D/P units are used by many instrument manufacturers as
the basic differential pressure sensing devices for indicators,
recorders, transmitters or controllers.
Meriam’s 1226X Explosion-Proof Indicating Switch is CSA and U.L. listed,
meeting N.E.C. requirements for Class I, Division I, Group B or Group D
hazardous environments. The explosion-proof housing is made from a
strong, lightweight aluminum alloy that is both non-rusting and
non-sparking. A large glass window provides full viewing of the 6"
indicator. Wall, panel or pipe mounting can be supplied. |
