Photohelic Gauge

Photohelic gauge switch (SERIES 3000MR & 3000 MRS) uses solid state technology and combines 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. Photohelic gauge switch 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 and include 18-inch (45 cm) cable assemblies for electrical connections.

Photohelic gauge switch are 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).

Gauge reading unaffected by switch operation and will continue to read pressure even during power loss

Zero and range adjustments outside of gauge means no disassembly in normal service

Solid state design allows for switching in high cycle rate applications without degradation
