Dwyer 3050MRS Photohelic Switch/Gauge 0 to 50 inch

Series 3000MR/3000MRS Photohelic® Switch/Gage

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

Model	Description
3050MRS-50 inch	Pressure Switch/Gage,Range 0-50 inch, 1.0 minor divisions.

Includes

mounting ring, snap ring
18" 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)
(3) 6-32 x 5/16" RH machine screws (surface mounting)

he Series 3000MR Photohelic® Switch/Gage 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" hole or surface mounted with hardware supplied. 3000MR models employ versatile electromechanical relays with gold over silver contacts - ideal for dry circuits.

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.

Precision Pressure Measurement and Control

The Dwyer 3050MRS Photohelic Switch/Gauge provides accurate monitoring and control of pressure within air and non-corrosive gas systems. With an analog display and adjustable dual SPDT set points, this device supports efficient automation and system protection in a wide array of industrial processes.

Durable Construction for Industrial Use

Engineered with a die cast aluminum housing and clear acrylic front, the 3050MRS is built to withstand harsh industrial conditions. The general-purpose enclosure, neoprene seals, and anodized finishing enhance the instruments longevity and reliability in various installation environments.

Easy Installation and Versatile Application

Designed for user convenience, the 3050MRS includes a mounting bracket and is panel mount-ready. Its external zero adjustment screw and screw terminal electrical connections facilitate straightforward setup, while compatibility with standard 1/8 NPT connections ensures seamless integration.

FAQs of Dwyer 3050MRS Photohelic Switch/Gauge 0 to 50 inch:

Q: How do I install the Dwyer 3050MRS Photohelic Switch/Gauge?

A: The 3050MRS is designed for vertical panel mounting using the supplied bracket. Ensure both the high and low pressure connections utilize the 1/8 NPT female fittings, and make electrical connections using the screw terminals as outlined in the instruction manual.

Q: What is the intended usage of the 3050MRS model?

A: This instrument is intended for accurate monitoring and control of pressure levels in air and non-corrosive gas systems across industrial and commercial settings, such as HVAC, filter monitoring, and process automation.

Q: When should I adjust the zero setting on the gauge?

A: Zero adjustment should be performed during installation or routine maintenancesimply use the external screw to align the gauge to zero when there is no applied pressure, ensuring measurement accuracy.

Q: Where can I use the Dwyer 3050MRS in terms of environmental conditions?

A: The gauge can be deployed in environments with ambient temperatures ranging from 20F to 120F (-6.67C to 48.89C), provided it is not exposed to substances that could damage its acrylic or neoprene components.

Q: What is the maximum pressure this gauge can safely handle?

A: The Dwyer 3050MRS has a maximum pressure rating of 25 psi (1.72 bar), making it suitable for a range of moderate-pressure applications while avoiding exposure to higher pressures that could damage the device.

Q: How do the adjustable set points work in the 3050MRS?

A: You can set two independent SPDT switch points anywhere within the 050 in. w.c. scale. These trigger electrical contacts, automating control functions like alarms or device activation based on changing pressure levels.

Q: What are the benefits of using a factory-calibrated gauge like the 3050MRS?

A: Being factory-calibrated ensures high measurement accuracy (2% of full scale) right out of the box, reducing installation time and maintenance while providing reliable performance for precise process control.
