Overview
Details for EP2101S
EP | Analog In | 3-15/0-20psi | Vent on Power Fail
Description
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 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.
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)
Application
- Hospitals
- Schools
- Pneumatic dampers/actuators
