Principle of operation
Mounted in-line between the cylinder and the
control valve, the sensor will give an output
when the pressure in this line is exhausted
and the cylinder is at end of stroke.
For the correct usage of sensors on a falling
pressure, it is recommended that the practical
cylinder load is limited to 60% of the
theoretical force.
