Pressure Monitoring | Electropneumatic Transducers

EP3 SERIES

Micro-Controlled with High-Performance,
Low-Power Coil Poppet Valve Technology

EP3

Observe handling precautions for static sensitive
devices to avoid damage to the circuitry which
would not be covered under the factory warranty.

Field-selectable

Field-selectable 4 to 20 mA/
0-5 V/0-10 Vdc input for
application exibility

Quiet operation

Poppet valve technology for quiet
operation

Manual override

Manual override with set and hold
feature…great for commissioning
leaky systems

APPLICATIONS

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

The EP3 Series combines a microcontroller with high performance,
low power coil poppet valve technology to create a system with
unparalleled accuracy and proven reliability. The poppet valves used
in the EP3 consume no air, eliminating unnecessary air losses in the
system and allowing for efficient, long-term operation. The EP3 permits
versatility, since all models feature manual override and a tri-state
control option. The LCD provides easy visibility and the LED indicators
provide visual status of valve operation in manual or automatic mode.
All models come with SnapTrack housing and optional covers are
available.
