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.
The Series 1226 Differential Pressure Indicating Switches are used for
on-off control or alarm. They also indicate flow, liquid level or other
process variables. These units are furnished with one or two SPDT type
switches with actuation set points easily adjustable over most of the
range of the instrument. The calibrated travel of the pointer is 270
degrees, which gives good differential pressure indication and switch
resolution. Dials can be supplied with linear scales for differential
pressure, square root scales for flow, or custom scales for level. The
1226 Series Switches are used extensively in power plants, compressor
stations, and cryogenic applications.
be supplied. The unit is compact and has 270° pointer movement for
greater resolution. |
