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
FEATURES
● Field-selectable 4-20mA/0-5V/0-10VDC input for application flexibility
● 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 fixed 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)
Micro-Controlled With High-
Performance, Low-Power Coil
Poppet Valve Technology
EP Series transducers are sold as an open device.
Observe handling precautions for static sensitive
devices to avoid damage to the circuitry which
would not be covered under the factory warranty.
