- System Sensor® EPS40-2
System Sensor® Pressure Switch, 250 psi, 3 psi at 10 psi/6 psi at 100 psi Differential, 300 psi Maximum, SPDT, 10 A, 1/2 hp at 125/250 VAC/2.5 A at 6/12/24 VDC Contact, -40 to 160 deg F, 1/2 in MNPT, Reinforced Nylon Connection, NEMA 4, 5.12 in H x 3.325 in W x 4.25 in L
The EPS40-1 has a single SPDT switch while the EPS40-2 model contains two SPDT switches. The EPS40 series features field adjustable pressure sensitivity to provide an alarm response between 10 and 100 psi. All models are factory set for use in a nominal 40 psi system. The EPS40-1 is factory set to respond at 30 psi at decreasing pressure while the EPS40-2 is factory set to respond at 50 psi on rising pressure and 30 psi at decreasing pressure. The pressure adjustment wheel requires no special tools and does not affect switch synchronization on the EPS40-2. The EPS40-1 and EPS40-2 supervisory pressure switches are NEMA 4 rated. Adjustable response 10 to 200 psi Sensitivity adjustment wheel, no special tools required Reinforced diaphragm resists pressure spikes Two conduit entrances Both one and two-switch models available Standard/Approvals: UL/ULC Listed, FM Approved, LPCB, G4020028-27 VDS, 7770-1209:147 Application: For use in dry pipe systems or pressure tanks and water pressure supplies of automatic water control valves
