Dwyer 3000MR Photohelic,Switch/Gauge 0 to 60 PAC

Series 3000MR/3000MRS Photohelic® Switch/Gage

Combines Differential Pressure Gage with Low/High Set-Points, Compact Size

Model	Description
3000MR-60PA	Pressure Switch/Gage, Range 0-60 Pa, 2.0 minor divisions.

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 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.

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).

Included Accessories: mounting ring, snap ring; 18" (45 cm) cable assembly; (2) 3/16" tubing to 1/8" NPT adapters; (2) 1/8" NPT pipe plugs; (4) 6-32 x 1-1/4" RH machine screws (panel mounting); and (3) 6-32 x 5/16" RH machine screws (surface mounting). 

 

Versatile Pressure Measurement and Control

The Dwyer 3000MR Photohelic provides simultaneous visual monitoring and automatic pressure control in air handling systems and process applications. The analog dial displays real-time differential pressure, while integrated SPDT snap switches enable precise setpoint management, making it invaluable for critical safety and automation tasks.


Durable and Reliable Design

Engineered from die-cast aluminum and featuring a black textured finish, the Dwyer 3000MR is designed to withstand harsh industrial environments. Its IP54-rated enclosure ensures resistance against dust and splashing water, guaranteeing dependable operation across a wide temperature range and minimizing maintenance requirements.


Easy Installation and Adjustment

The switch/gauge supports both panel and surface mounting for versatility. With external zero adjustment, calibration can be performed without disassembly. Included accessoriesmounting brackets, snap ring, and manualstreamline the installation process, while the screw terminal electrical connections simplify wiring.
