APPLICATIONS
Multi-point
calibration
Multi-point calibration; 3 to 15 psi
(5-point calibration) and 0 to 20
psi (6-point calibration)
Pressure loss
alarm
Pressure loss alarm provides a
contact closure if the EP3 is unable
to achieve the desired output
within a fixed length of time
Fail-safe vent
Fail-safe vent solenoids bleed
branch pressure on power failure
for added safety
Observe handling precautions for static sensitive
devices to avoid damage to the circuitry which
would not be covered under the factory warranty.
The EP2 Series electropneumatic pressure transducer uses microcontrolled poppet valve technology for highly accurate pressure
sensing in multiple applications. The poppet valves consume no air,
eliminating unnecessary air losses in the system and allowing for stable
and reliable operation. The EP2 comes installed on standard SnapTrack,
and an optional dust cover is available to protect from the environment.
An LCD display and LED indicators make it easy to read system status at
a glance.
