SYSTEM SENSOR EPS402

Product Overview

 The EPS40 Series supervisory pressure switches are offered in single- and dual-switch versions to accommodate different system requirements. The EPS40-2 is equipped with two SPDT switches. These devices provide field-adjustable pressure sensitivity, allowing supervisory response settings from 10 to 100 PSI. All models are factory configured for use in nominal 40 PSI systems. The EPS40-1 is preset to activate at 30 PSI on decreasing pressure, while the EPS40-2 is preset to operate at 50 PSI on rising pressure and 30 PSI on decreasing pressure. A built-in, tool-free adjustment wheel allows pressure settings to be modified without affecting switch synchronization on the EPS40-2.
