DescriptionThe four-channel Bently Nevada™ 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 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
Ordering Considerations
l For I/O Modules with External Terminations, order the External Termination Blocks and cable separately for each I/O Module.
l For Internal Barriers, refer to the 3500 Internal Barrier Datasheet (document 141495).
l The Recip Rod Position Monitor requires version 3.20 or higher of the 3500 Rack Configuration Software.
l Rod Position Single 2 and Rod Position Pair 2 channel types require Rack Config release 6.0 or later.
The lower limit for machine speed is 60 RPM in the standard product. For machine speeds down to 30 RPM, modification 135M8199-01 is required.
