Dwyer 3000MR Photohelic,Switch/Gauge 0 to 500 PAC

Series 3000MR/3000MRS Photohelic® Switch/Gage

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

Model	Description
3000MR-500PA	Pressure Switch/Gage, Range 0-500 Pa, 10.0 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).

Reliable Pressure Control for Critical Environments

The Dwyer 3000MR Photohelic Switch/Gauge is ideal for monitoring and controlling low-pressure air and compatible gases in demanding environments. Trusted applications include HVAC systems, clean rooms, air filter checks, and automated process control, providing swift switching within one second and precise analog readouts up to 500 Pa. Factory calibration and superior build quality make it a dependable solution for industrial use.

Flexible and Durable Design

Constructed from die-cast aluminum with a polycarbonate lens, this gauge ensures longevity in rugged settings. It is designed for surface or flush mounting, with a vertical orientation preferred. Accessories supplied, like mounting hardware and an instruction manual, streamline installation and setup. IP54 protection further enhances longevity in industrial conditions.

FAQs of Dwyer 3000MR Photohelic,Switch/Gauge 0 to 500 PAC:

Q: How do I install the Dwyer 3000MR Photohelic Switch/Gauge?

A: The gauge can be surface or flush mounted using the included hardware. A vertical mounting orientation is recommended for optimal accuracy. Simply follow the provided instruction manual for step-by-step guidance.

Q: What is the process for zero adjustment on this gauge?

A: Zero adjustment is easily accessible through a front screw. Ensure the gauge is properly mounted and pressure lines are vented before adjusting, ensuring the needle sits at zero with no pressure applied.

Q: Where can I use the Dwyer 3000MR Photohelic in my facility?

A: This device is commonly used in HVAC systems, clean room environments, air filter monitoring stations, fan controls, and process control applicationsanywhere precise, real-time pressure measurement of air or compatible gases is necessary.

Q: What is the benefit of the fast response time?

A: A response time of less than one second ensures immediate switching and display changes as conditions vary, which is crucial for maintaining stable and controlled environments, particularly in sensitive applications like clean rooms or process automation.

Q: Can the Dwyer 3000MR handle high-pressure applications?

A: No, this gauge is designed for pressures up to 172 kPa (25 psi) and a measurement range of 0 to 500 Pa, making it ideal for low-pressure air and compatible gases. Using it above its rated pressure could result in damage or loss of accuracy.

Q: What are the power requirements for operation?

A: The 3000MR operates on either 120 VAC or 240 VAC at 50/60 Hz. Consult the instruction manual to set up the proper power configuration for your facility.

Q: What makes the Dwyer 3000MR suitable for industrial use?

A: Its industrial-grade construction, robust switch ratings, IP54 enclosure protection, and compliance with CE and RoHS standards ensure reliability, durability, and compatibility with industrial automation and monitoring systems.
