General Description
Threshold Sensors – PWS
The plug-in threshold sensors provide feedback information
on pneumatic cylinder status in one of three possible outputs
. . . pneumatic, electric, or electronic. Mounted into the
cylinder port, these devices monitor the back pressure of the
cylinder's exhaust. When the cylinder's piston stops, the back
pressure rapidly drops and the threshold sensor provides
the desired output. Ideal for variable stroke applications
such as robotics where other sensor type devices such as
limit switches are impractical, these devices provide a signal
whenever the cylinder stops motion.
The threshold sensor consists of two complementary sub
assemblies (1) the banjo fitting and (2) the plug-in sensor
element. In all cases, the sensor is easily plugged into the
banjo fitting and locked in place with a spring clip. The banjo
fitting is designed to accept (piggy backed) other functional
fittings such as flow controls or blocking valves. Simply select
the sensor based on the type feedback signal that best fits
the application.
