EP-500
The electric-pneumatic converter EP-500 is a device that outputs air pressure proportional to the command when given a voltage command.
Features of the EP-500
- Immediately deliverable
- Analog Output
- Compatible
- Enables highly accurate and stable pressure control with a feedback system using a semiconductor pressure sensor and an electronic circuit.
- Using a piezoelectric element as an actuator of the nozzle flapper mechanisms, the EP-500 is highly resistant to external vibration, compact, and easily mountable.
- Equipped with a centralized exhaust system to keep the surrounding environment clean.
- Compatible with previous models EP-300 and EP-400
Wide range of applications that require pressure control such as:
- Air brake control
- Touch-pressure control
- Force balance control such as dancer mechanism
