Crouzet Pneumatic Position Detector
The Crouzet 81 series 3/2 port pneumatic position detector has operating pressure ranging between 0.18bar and 18bar. It is a normally closed position detector and that has a lever with a plastic roller. This detector is fitted in-line between the cylinder and the control valve and the sensor gives an output when the pressure in this line is exhausted and the cylinder is at the end of the stroke. It is recommended that the practical cylinder load is limited to 60% of the theoretical force for the correct usage of sensors on falling pressure.
