Pneumatic positioner CRP-3/M, CRP-3/M-EP

electropneumaticrotary

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
