3500/72M Recip Rod Position Monitor

The four-channel 3500/72M Recip Rod Position Monitor accepts input from proximity transducers, conditions the signal to provide dynamic and static position measurements, and compares the conditioned signals with user-programmable alarms.
Each channel, depending on how you configure it, typically conditions its input signal to generate various parameters called measured values.
Use the 3500 Rack Configuration Software to:
Configure alert setpoints for each active measured value and danger setpoints for any two of the active measured values.
Protect reciprocating compressors by continuously comparing monitored parameters against configured alarm setpoints to display alarms and trigger relays, if needed.

Monitor the condition of essential reciprocating compressor machinery.

The 3500/72M Recip Rod Position Monitor meets API 618 requirements for reciprocating compressors. It measures:
Rod position
Rod drop
Hyper-compressor
