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. Versatile electromechanical relays with gold over silver contacts - ideal for dry circuits. 

Dwyer 3010MRS Photohelic, Switch/Gauge 0 to 10 in W.C.

Using solid state technology, there Series 3000MR and 3000MRS Photohelic switch/gauges 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). 

Precise Differential Pressure Monitoring

The Dwyer 3010MRS Photohelic offers precise measurement and control of differential pressure across a 0-10 inches Water Column range. It uses diaphragm sensor technology for reliable, accurate readings (2% full scale) displayed on a clear analog dial. Its robust construction suits harsh industrial environments, making it ideal for monitoring filters, fans, blowers, and various process pressures.


Versatile Control and Simple Adjustability

Engineered with SPDT snap switches and external knob set point adjustment, the 3010MRS Photohelic simplifies system control. Users can set switch points for alarms or automatic controls without opening the enclosure. The switches operate directly from the contact voltage, eliminating complex wiring or power needs for the gauge itself.
