EPS120-1 and EPS120-2
Supervisory
Pressure Switches
System Sensor EPS120 Series 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.
Features
• Pressure adjustment wheel, no special tools required
• Field adjustable pressure sensitivity
• Factory set for use in a nominal 115 psi system
• Reinforced diaphragm resists pressure spikes
• Two conduit entrances provided
• NEMA 4 rated
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 and 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 while 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.
