U **Division 1 Rating** 

- U **Single or Dual Setpoints, Tamper Resistant** 

- U **Heavy-Duty Enclosure** 

- U **Rated NEMA 4X, 7, 9 (IP66)** 

- U **Terminal Block Wiring** 

- U **High-Temperature Operation to 200°C (392°F) Process Temperature (Stainless Steel Model Only)** 

PSW-700 Series pressure switches are built for the rugged industrial setting. The internal setpoints allow adjustments while keeping the electrical component isolated from the environment. Both the internal and external setpoints have a range scale, allowing fast, easy setup. 

## **SPECIFICATIONS** 

**Approvals:** UL listed; Class I, Division 1 and 2, Groups B, C and D; Class II, Groups E, F and G; Class III 

**Repeatability:** ±1% range
