• PSP13 — Dual value type (two switches in one body)
Brand : Clark Automation Technology Co., Ltd.
The PSP11 single-value ordinary pressure switch has a simple structure, stable performance, and good long-term stability. It is equipped with a locking adjustment nut and can maintain the stability of the set value even in environments with large vibrations for a long time.
The PSP Series pressure switches are an economical solution for process plants and OEM equipment. The rugged, one-piece housing features a sloped cover for wiring access. A variety of microswitch and process connection options make this versatile series ideal for applications requiring a rugged, weatherproof design. The all-weather series offers a wide selection of microswitch and process interface options to meet diverse needs. Widely adjustable deadbands cater to pump applications, and pressure switches with smaller deadbands are also available. The PSP Series is widely used in heat tracing, freeze protection, process equipment (pumps, compressors), hydroelectric power plant pressure relief systems, alarm panel inputs, and flame arresting systems. Its robust design makes wiring easier.
