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

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

Pressure switch/gage, range 0-10" w.c., .20 minor divisions.

Model: 3010MRS

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.

FAQ's of Dwyer 3010MRS Photohelic,Switch/Gauge 0 to 10 in W.C:


Q: How does the Dwyer 3010MRS Photohelic gauge measure differential pressure?

A: The 3010MRS Photohelic gauge uses a diaphragm-based sensor to accurately detect differential pressure between two points, displaying the measurement on an analog scale ranging from 0 to 10 inches of water column (W.C.).

Q: What applications is the Dwyer 3010MRS suitable for?

A: It is commonly used for filter monitoring, fan and blower control, and vacuum or pressure monitoring involving steam, oil, or gas, making it ideal for various industrial and process control environments.

Q: When should I use the external knob for set point adjustment?

A: Use the external knob anytime you need to adjust the switch activation points for the desired pressure threshold, allowing you to fine-tune the control or alarm function without disassembling the unit.

Q: Where should I install the Dwyer 3010MRS Photohelic gauge?

A: The gauge can be installed on a flush or surface mount, preferably in locations where it can easily connect to the pressure source via the two 1/8" NPT female side ports. Ensure the environment is within the specified operating temperature range of 20F to 120F (-6.7C to 48.9C).

Q: What process is involved in powering the switches of this gauge?

A: The gauge itself does not require external power; however, the integrated SPDT snap switches operate using the contact voltage from your system, making installation straightforward and flexible.

Q: How is the Dwyer 3010MRS Photohelic gauge beneficial for industrial applications?

A: Combining reliable pressure measurements with automatic control switching, it enhances operational efficiency by providing immediate feedback and activation for process monitoring or protection tasks, reducing downtime and maintenance needs.
