Rod Drop Indicator

An Compressor Rod Drop Indicator is used to protect rotating rods or shafts against wear and save maintenance cost and possible compressor damage or engine damage. Rod drop indicators represent just a small investment against shaft wear compared to the high cost of reworking or exchanging compressor or engine shafts.

The Exline 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. This contact creates a friction temperature which melts the fuse-metal plug in the device. A pressure drop in the pneumatic control system results. This pressure drop can be used to shut down the equipment or sound an alarm.  A flat end indicator can be used to detect excessive end play in rotating equipment.
