Dwyer 3001MR Photohelic Differential Pressure Switch/Gauge Range: 0-1"w.c. About

Dwyer 3001MR Photohelic Differential Pressure Switch/Gauge Range: 0-1"w.c.

Pressure switch/gage, range 0-1"w.c..02 minor divisions. 

Model: 3001MR

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 3001MR Pressure switch gage range 0 to 1 in WC

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. 

 



Accurate Dual Functionality

The Dwyer 3001MR Photohelic acts both as a differential pressure gauge and switch, allowing users to monitor pressure and control equipment simultaneously. Its analog dial delivers clear readings within a 0-1" w.c. range, and the two SPDT snap-action switches enable independent setpoint adjustments for custom control requirements.


Built for Industrial Applications

Constructed with a durable die-cast aluminum case and a scratch-resistant polycarbonate lens, the 3001MR is designed to withstand harsh operating environments. Its 4-inch diameter and panel mount design make it suitable for various industrial setups, including those requiring pressure monitoring for steam, oil, or gas.


Simple Setup and Operation

Featuring external zero adjustment and easily accessible setpoint knobs, the 3001MR ensures straightforward calibration and fast on-site adjustments. Mounting screws and an instruction manual are provided for quick installation, and its external screw terminal electrical connections make wiring straightforward for users.

FAQ's of Dwyer 3001MR Photohelic Differential Pressure Switch/Gauge Range: 0-1"w.c.:


Q: How do I adjust the pressure switch setpoints on the Dwyer 3001MR Photohelic?

A: Setpoints can be adjusted using the external knobs located on the face of the gauge. These knobs allow you to tailor activation points for the two SPDT snap-action switches without opening the enclosure, ensuring easy and accurate control.

Q: What types of media can the Dwyer 3001MR Photohelic measure?

A: This model is suitable for measuring the differential pressure of steam, oil, and gas. Its industrial-grade construction and Buna-N seals ensure compatibility with common system fluids found in HVAC and process applications.

Q: When is an external power supply required for the 3001MR?

A: An external power supply is not needed for pressure measurement via the analog dial, but it is required to operate the snap-action switch functions. This allows the gauge to monitor pressure independently, while the switching functions can trigger external controls as needed.

Q: Where should I mount the Dwyer 3001MR for optimal performance?

A: The gauge is designed for vertical, panel-mounted installation. Ensuring correct orientation as specified in the manual maintains accuracy and prolongs the lifespan of the sensor.

Q: What is the overpressure limit of the 3001MR, and why is it important?

A: The overpressure limit is 10 psi (0.69 bar). Staying within this limit prevents damage to the differential pressure sensor and ensures reliable long-term performance in your system.

Q: How accurate is the Dwyer 3001MR Photohelic Differential Pressure Gauge?

A: It offers an accuracy of 2% of the full scale, providing precise pressure readings that enable optimized control and monitoring in critical applications.

Q: What accessories are included with the 3001MR Photohelic during purchase?

A: The product comes complete with mounting screws and a detailed instruction manual, ensuring you have what you need for straightforward installation and commissioning.
