Application
The threshold sensor provides electrical or pneumatic
feedback information on pneumatic (air) cylinder status.
These devices monitor the back pressure of the cylinder's
exhausting chamber. When the cylinder stops, the back
pressure drops and the threshold sensor provides the
desired output. Ideal for variable stroke applications. The
banjo fitting and the feedback element are two separate
subassemblies, giving the user flexibility between electrical
and pneumatic outputs as feedback.
Mounting
Banjo fittings in 10-32 to 1/2" pipe sizes are designed to be
installed directly into actuator ports (up to 5" bore cylinders).
The banjo fitting can accommodate other functional fittings
and components such as right angle flow control valves or
blocking valves. Banjo fittings screw into actuators using
an Allen wrench or 5/16" hex head wrench for 10-32 size.
Electrical or pneumatic feedback element snaps into place
using a locking clip.
Operation
Pneumatic sensors have a continuous pressure signal
applied to the sensor device. Electrical sensors have a
continuous electrical signal applied to the sensor device. The
threshold sensor assembly mounted directly into the cylinder
Port provides an output signal S, which can be pneumatic or
electrical, when the falling back pressure in the exhausting
chamber of the cylinder reaches the operating threshold
(approximately 6-9 PSIG). (The device is a normally passing
device. The output is only on when there is nearly zero
pressure at the cylinder.)
