Using solid state technology, the SERIES 3000MR & 3000 MRS Photohelic® Switches/Gauges
combine the functions of a precise, highly repeatable differential pressure switch with a large
easy-to-read analog pressure gauge employing the durable, time-proven Magnehelic® gauge
design. Switch setting is easy to adjust with large external knobs on the gauge face. Gauge reading
is unaffected by the 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 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. 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).
