Ok Rod Reversal Experts!
I would like to know if there is an existing technology for continuously monitoring the rod reversal of the pin in the cross head bushing that facilitates the lubrication of this section of a reciprocating compressor cylinder piston drive line mechanism.
We have experienced a condition of non-rod reversal on one of our compressors that resulted in the cross head bushing to fail due to lack of lubrication.
I have a good concept of the dynamics within this mechanism and understand that an accelerometer at 45 degrees in line with the piston shaft will show you the loading and unloading impacting in the peak to peak sine wave as a 2X RS component.
My question specifically is: Does a monitoring technology exist that one can install on the compressor that will monitor this rod reversal on a continuous basis and alarm when non-rod reversal occurs without physically identifying the condition with test equipment?

there are others listed . . .
good luck!

Other option is to continuously monitor the temperature of pin and activate an alarm at a set value. In this case the signal has to be transmitted from the moving corss-head/con-rod to the static receiver.
