About Series 3000MR/3000MRS Photohelic Switch/Gage

Series 3000MR/3000MRS Photohelic Switch/Gage

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

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 Control for Industrial Applications

Engineered for a range of usessuch as HVAC diagnostics, clean room monitoring, and process controlthe Series 3000MR/3000MRS Photohelic Switch/Gage delivers both monitoring and switching functionalities. Its instant response time and dual SPDT snap action switches facilitate efficient process management, ensuring timely interventions and optimal system performance.

User-Friendly Operation and Adjustment

Equipped with external set point adjustment knobs on the faceplate, users can easily and accurately set threshold points without disassembling the device. The analog display with dual set point indicators provides clear visual status, making operation straightforward and minimizing training time for installers and operators.

Robust Construction with Safety and Compliance

Encased in a machined die cast aluminum body with a durable black finish and an acrylic lens, this Photohelic Switch/Gage resists environmental wear. Overpressure protection and RoHS/CE certifications assure both safety and global compliance, while the NEMA 2/IP54 rating offers protection from dust and drips in industrial settings.

FAQs of Series 3000MR/3000MRS Photohelic Switch/Gage:

Q: How do I adjust the set points on the Series 3000MR/3000MRS Photohelic Switch/Gage?

A: Set points can be adjusted externally using the dedicated knobs on the front faceplate. This allows for precise and convenient adjustment of pressure thresholds without needing to open or remove the gauge.

Q: What types of applications are best suited for this Photohelic Switch/Gage?

A: This model excels in HVAC system monitoring, clean room pressure maintenance, filter status indication, and other process control tasks involving the measurement of air or compatible gases.

Q: Where should the device be mounted for optimal performance?

A: Vertical mounting is preferred to ensure the best accuracy and performance. The device supports both flush and surface mounting, and includes a mounting bracket and necessary hardware.

Q: What is the process for wiring the SPDT snap action switches?

A: Wiring is performed using provided terminal screws. Each gauge includes two SPDT switches, which can be connected to external control systems or alarms for automation or notification purposes. Electrical ratings must be observed for safe operation.

Q: When can I expect an instantaneous response from the switch contacts?

A: The integral snap action switches provide instantaneous response as soon as the measured differential pressure passes the configured set point, guaranteeing prompt feedback in dynamic environments.

Q: What are the benefits of the NEMA 2/IP54 enclosure rating?

A: The NEMA 2/IP54 rating means the enclosure protects against dust, falling dirt, and light splashing of liquids, making it suitable for many industrial, laboratory, or commercial indoor locations.

Q: How does the built-in overpressure protection work?

A: The Photohelic Switch/Gage is engineered with safeguards to prevent damage from pressure spikes, maintaining the integrity of internal components and ensuring long service life even in demanding conditions.
