Electropneumatic Transducers
Micro-Controlled With HighPerformance, Low-Power Coil
VERIS INDUSTRIES
Poppet Valve Technology
DESCRIPTION
The EP2 Series electropneumatic pressure transducer uses micro-controlled 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 is 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.
APPLICATIONS
● Hospitals
● Schools
● Pneumatic dampers/actuators
PRESSURE
EP2
FEATURES
● Field-selectable 4-20mA/0-5V/0-10VDC input for application exibility
● Poppet valve technology for quiet operation
● Manual override with set and hold feature...great for commissioning
those leaky systems
● Multi-point calibration; 3-15 psi (5 point calibration) and 0-20 psi
(6 point calibration)
● Pressure loss alarm provides a contact closure if the EP2 is unable to
achieve the desired output within a xed length of time
● Failsafe vent solenoids bleed branch pressure on power failure for added safety
● Optional transparent plastic dust cover (AA43) protects units from dust
and tampering (required for CE)
