CRP-3/M & CRP-3/M-EP
The CRP positioner consists of a diaphragm exposed to the regulating signal pressure, of a feedback spring and a double acting spool valve connected to the diaphragm and feedback spring by the rod.
The CRP-3/M-/EP positioner (fig. 2), modulating type, is made of two units:
• pneumatic positioner CRP series (fig. 1);
• electropneumatic EP series.
The two units are assembled together. This positioner is connected to a double-acting rotary actuator and it is based on the balanced-forces principle.
- Air supply pressure: 2 to 7 barg
- Environmental protection: IP 65
- Input signal: 4 to 20 mA (4 to 12 mA / 12 to 20 mA as optional)
- Operating temperature: -10°C to +70°C (wide temperature ranges are available on request)
- Sensitivity: ≤ 0,3% on the whole stroke
