Dwyer Instruments CXA-R1 Pressure Switch
The Dwyer CXA-R1 Pressure Switch is a contractor-grade water pump pressure control designed for heavy-duty applications. This normally open switch features a 15-80 psig range and is engineered with a DPST snap action to maintain precise system pressure. The 15-30 psig adjustable deadband allows technicians to fine-tune the differential, reducing short-cycling in pump control systems. Built for versatility, the CXA-R1 includes a 1/4" female NPT process connection and high-capacity electrical ratings, including 20A at 120 VAC and 12A at 240 VAC. The silicone and stainless steel wetted materials ensure chemical compatibility in various water conditions, while the CE certified enclosure supports temperatures up to 140°F. Whether you are replacing a well pump switch or installing a new pressure monitoring solution, this Dwyer Instruments unit provides the adjustable pressure settings and terminal durability required for professional HVACR and plumbing service.
Key Benefits:
- Flexible Differential: The adjustable deadband of 15-30 psi prevents rapid pump cycling and extends motor life.
- High Amperage Rating: Rated up to 20A, making it suitable for high-draw water pump control without external relays.
- Robust Construction: Features a snap action switch with silicone and steel wetted parts for long-term reliability in damp environments.
- Simple Integration: Standard 1/4" NPT Female connection allows for fast installation on most residential and commercial pressure tanks.
- Versatile Mounting: The internal mechanics are not position sensitive, allowing for horizontal or vertical orientation in tight mechanical rooms.
Common Questions:
How do you adjust the pressure settings on the CXA-R1?
The increase and decrease of the set point and deadband are handled via internal adjustment screws. This allows service techs to calibrate cut-in and cut-out pressures to the specific requirements of the piping system.
Is this switch suitable for outdoor use?
While the CXA-R1 is built for durability, it is primarily designed for indoor or protected environments with a maximum operating temperature of 140°F. Ensure the electrical connections are shielded from direct weather exposure.
Can this be used for 3-phase pump applications?
Yes, the Dwyer CXA-R1 is rated for 9.6 A @ 240 VAC (3-phase), providing flexibility for industrial and agricultural pumping configurations.
