Typical Applications of SOR Pressure Switches

1. Industrial Process Control is used to monitor and control pressure in pipelines, tanks, and reactors. Ensures safe operation by activating alarms or shutdown systems when pressure exceeds set limits2.
2. Pumps and Compressors protect pumps from running dry or over-pressurizing. Common in cooling water systems, boiler feed pumps, and air compressors.
3. Oil & Gas Industry Applied in upstream and downstream operations to safeguard equipment against overpressure, detect leaks, and maintain system integrity in harsh environments.
4. Chemical and Petrochemical Plants With NEMA 4/4X and IP65/IP66 enclosures, these switches withstand corrosive atmospheres and outdoor exposure, making them reliable for chemical dosing, storage, and transfer systems.
5. Power Generation Used in steam and gas turbine systems, boiler monitoring, and auxiliary equipment to maintain stable and safe operating conditions.
6. HVAC and Building Systems provides pressure monitoring in chillers, boilers, and air handling units. Ensures energy efficiency and safety in commercial facilities.
7. Water and Wastewater Treatment Controls pump stations, filtration systems, and distribution networks. Prevents overpressure damage and ensures continuous service.

SOR Pressure Switch – FAQ

Q1. What is a pressure switch, and how does it work?

A pressure switch is a device that monitors system pressure and activates an electrical contact when a setpoint is reached. SOR switches use a piston-actuated, force-balance mechanism sealed by a diaphragm and O-ring to ensure accuracy and durability.

Q2. What media can SOR pressure switches handle?

Standard models are suitable for air, oil, water, and non-corrosive fluids. For corrosive or special media, optional stainless steel, Monel, or welded diaphragm systems are available.

Q3. What enclosure ratings are available?

• NEMA 1 – General indoor use
• NEMA 4 / 4X – Waterproof, dust-tight, corrosion-resistant
• NEMA 7 / 9 – Explosion-proof for hazardous areas. Ingress protection ranges from IP54 to IP66, depending on the model.

Q4. What pressure ranges are covered?

SOR offers a wide span, from vacuum service up to high-pressure ranges exceeding 10,000 psi, depending on the spring code (K2, K3, K5, K45, K116, etc.).

Q5. Can the deadband (differential) be adjusted?

Yes. Deadband values depend on the piston/spring combination and are typically expressed at mid-range. Some models allow manual reset for added safety.

Q6. How long is the service life?

SOR switches are designed for long-term continuous duty, resistant to vibration, overpressure, and harsh environments. Many units operate reliably for millions of cycles without recalibration.

Q7. Do SOR switches require maintenance?

Routine maintenance is minimal. Periodic inspection of electrical connections and diaphragm integrity is recommended. No special tools are required for installation or adjustment.

Q8. Are custom configurations available?

Yes. SOR offers Engineered-to-Order options, including special housings, diaphragm systems, switching elements, and process connections.

Q9. What certifications are available?

Depending on the model, UL, CSA, ATEX, IECEx, and other global approvals are required for hazardous locations.

Q10. What is the warranty?

SOR provides a 5-year warranty on most pressure and level switches, reflecting their reliability and build quality.
