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 3002MRS Photohelic, Switch/Gauge 0 to 2 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).

Industrial Accuracy and Reliability

Engineered for demanding environments, the Dwyer 3002MRS delivers reliable pressure measurement with an accuracy of 2% full scale. Its durable construction and electromechanical design ensure consistent performance when monitoring critical systems involving steam, oil, or gas.


Versatile Mounting and Easy Installation

The device can be flush- or surface-mounted to suit diverse industrial setups. Installation is straightforward with included mounting brackets and screws, and its screw terminal electrical connections simplify wiring for control circuits.


Dual Switch Control for Efficient Automation

Featuring two SPDT snap action switches, the 3002MRS enables automated, independent dual-setpoint pressure control. This provides added flexibility for protecting equipment or activating alarms when specific pressure thresholds are reached.
