Description
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:
l Configure alert setpoints for each active measured value and danger setpoints for any two of the active measured values.
l Protect reciprocating compressors by continuously comparing monitored parameters against configured alarm setpoints to display alarms and trigger relays, if needed.
l Monitor the condition of essential reciprocating compressor machinery.
The monitor channels are programmed in pairs and can perform up to two functions at a time. For example, channels 1 and 2 can perform one function while channels 3 and 4 perform another or the same function.
The 3500/72M Recip Rod Position Monitor meets API 618 requirements for reciprocating compressors. It measures:
l Rod position
l Rod drop
l Hyper-compressor
