Pressure Switches

EPS120 Series Supervisory Pressure Switch

EPS120 Series supervisory pressure switches are designed to supervise system air pressure in pipes or pressure tanks, as well as water or air pressure supplies of automatic water control valves.

EPS120 Series Supervisory Pressure Switch

EPS120 Series supervisory pressure switches are designed to supervise system air pressure in pipes or pressure tanks, as well as water or air pressure supplies of automatic water control valves. The EPS120-1 has a single SPDT switch, while the EPS120-2 model contains two SPDT switches. The EPS120 Series features field-adjustable pressure sensitivity to provide an alarm response between 10 to 200 psi. All models are factory set for use in a nominal 115 psi system. The EPS120-1 is factory set to respond at 105 psi at decreasing pressure. The EPS120-2 is factory set to respond at 125 psi on rising pressure and 105 psi on decreasing pressure. The pressure adjustment wheel requires no special tools and does not affect switch synchronization on the EPS120-2.
