Photohelic® Switch/Gages
|
|
3000MRS
|
Combines Differential Pressure Gage with
Low/High Set-points
|
|
|
|
Using solid state technology, the Series 3000MR and
3000MRS Photohelic® switch/gages
|
|
Combine the functions of a precise, highly repeatable
differential pressure switch with a large easy-to-read
|
|
analog pressure gage employing the
durable, time-proven Magnehelic® gage
design. Switch setting is easy
|
|
to adjust with large external knobs
on the gage face. Gage reading is unaffected by switch operation – will
|
|
indicate accurately even if power is
interrupted. Solid state design now results in greatly reduced size and
|
|
weight. Units can be flush mounted in
4-13/16” (122 mm) hole or surface mounted with hardware supplied.
|
|
3000MR models employ versatile electromechanical relays
with gold over silver contacts – ideal for dry circuits.
|
|
For applications requiring high cycle rates, choose
3000MRS models with SPST (N.O.) solid state relays. All
|
|
models provide both low and high limit control and
include 18-inch (45 cm) cable assemblies for electrical
|
|
connections.
|
|
|
|
Gage accuracy is +/-2% of full scale and
switch repeatability is +/-1%. Switch deadband is
one pointer width-
|
|
less than 1% of full
scale. Compatible with air and other non-combustible, non-corrosive gases,
they can be
|
|
used in systems with
pressures to 25 psig (1.725 bar). Optional construction is available for use
to either
|
|
35 psig (2.42 bar) or
80 psig (5.51 bar).
