 ELECTRONIC
COMPRESSOR ROD DROP INDICATOR
The
Exline Electronic Compressor Rod Drop Indicator is installed
directly beneath the compressor rod to detect wear.
If
wear occurs on the piston, piston riders, or cylinders,
the compressor rod drops and makes contact with the indicator.
Continuous temperature readout will trigger a shutdown
or an alarm upon temperature increase. Connect them to
existing control circuitry or have us install a complete
system, including a monitoring panel.
Durable No-Maintenance Design:
Standard units house a Type “J” ungrounded
thermocouple. The Electronic CRD is equipped with a standard
15' TFE-coated lead wire length that can be either encased
in a flexible braided stainless steel overlay or supplied
ready to be installed in metal conduit. The thermocouple
allows for a temperature range from approximately 32°
F to 1380° F.
Options:
Options include custom length lead-wire in 5’ increments.

Details
of Installation
Using the packing case nuts as mounting points, a bracket
can be fabricated to support the CRD directly under the
compressor rod. Two holes are drilled and tapped in the
surface of the bracket to attach the device. A shim stock
(for example .010) is inserted between the surface of
the compressor rod and curved surface of the device. The device is
positioned firmly against the shim stock and bolts are tightened. This permanently
positions the Electronic CRD into place. The shim is removed
and the device is wired into the existing monitoring system.
