Features:
- Reciprocating Compressor Rod Position Monitoring with Proximity Transducer Interface
- Four-Channel Signal Conditioning with Dynamic and Static Position Measurement
- Paired Channel Programming Supporting Simultaneous Dual Functions
The Bently Nevada 3500/72M 176449-08 operates as the Recip Rod Position Monitor in a 3500 rack, providing continuous piston rod position monitoring for reciprocating compressors. It 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 of the 3500/72M 176449-08, depending on how you configure it, typically conditions its input signal to generate various parameters called measured values. Seamless monitoring is standard with the 3500/72M 176449-08, and using the 3500 Rack Configuration Software will allow precise alert and danger setpoint configuration for each active measured value. The 3500/72M 176449-08 meets API 618 requirements for reciprocating compressors and has made improvements in rod position, rod drop, and hyper-compressor measurement capability within the 3500 rack.
The 3500/72M 176449-08 provides essential monitoring functions for reciprocating compressor protection, and is a critical component of the machinery protection path, directly affecting the proper, normal operation of the overall compressor monitoring system. One 3500/72M 176449-08 monitor module occupies a full-height slot in the rack and can be installed in any available monitor slot position.
For comprehensive reciprocating compressor protection applications, the 3500 System requires the 3500/72M 176449-08 monitor module configured with appropriate proximity transducers. In addition to standard single function operation, the paired channel configuration also performs simultaneous dual functions. The 3500/72M 176449-08 paired channel programming executes function assignment using the internal software configuration specified in the monitor options. Using this method, the channel pairing system continually processes transducer signals. If the system detects that monitored parameters exceed configured alarm setpoints, it will automatically trigger relay outputs and place an event in the System Event List.
The 3500/72M 176449-08 Bently Nevada Recip Rod Position Monitor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
