 DUAL
SENSOR ASSEMBLY
The
Exline Dual Sensor Assembly provides compact and practical
protection for piston pin bushings, cylinders, and pistons.
This assembly incorporates two devices as a single unit.
One senses high piston skirt temperature and the other
detects any wear resulting in piston overtravel.
Because the lower portion of the piston skirt does not
readily transfer heat to the cylinder wall and therefore
runs at a more consistent operating temperature, the temperature
sensor is installed on the inside diameter of the piston
skirt. Any excessive temperature rise of the piston skirt
will melt a fuse-metal alloy, permitting a spring-loaded
plunger to extend toward the inside of the piston. This
plunger then strikes a break-off dowel, creating a pressure
drop in the pneumatic control system that can be used
to shut down the equipment or sound an alarm. Excessive
downward travel of the piston will also create a pressure
drop by striking a separate break-off dowel located on
the same header of this “two-in-one” device.

Details of Installation
The Dual Sensor Assembly should be mounted at the bottom
of the cylinder directly below the end of the piston pin.
Mount the bracket at the bottom of cylinder and install
header on bracket. Drill and tap hole in piston skirt
to install striker sensor.* The striker should be located
directly above the break-off dowel adjusting screw. Plunger
of striker should have 1/16" clearance from adjusting
screw (shown in Figure A). Clearance between piston
and adjusting screw (shown in Figure B) should be
field adjusted to operating clearance. Install tubing to control system.
*See Striker Sensor on page 5, for “Details
of installation” and “Available Fuse Collar
Melting Temperatures” on page 4.
