PRODUCT DESCRIPTION
Reciprocating rod position monitor
Bently Nevada 3500/72M 176449-08 is a reciprocating rod position monitor. The monitor evaluates proximity-transducer signals for static and dynamic rod-position measurements. It compares values with alarms for reciprocating compressor monitoring. Channel functions are programmed in pairs, and the selected sensor sensitivity, target geometry and software configuration must match the measurement.
The official spare list identifies 176449-08 as the 3500/72M Recip Rod Position Monitor. Match its front module with the specified rear I/O. The record does not establish the supplied I/O option, delivered firmware revision or a lower-speed modification.

ACTUAL APPLICATIONS
Applications for 3500 rod position monitoring system
These applications describe manufacturer-documented family use. They do not establish that this exact ordering code was installed at a named customer site.
-
01 · ROD POSITION
Static and dynamic rod measurements
Compatible proximity transducers provide signals for the configured rod-position values. The paired channel arrangement and transducer scale factor must match the compressor installation. -
02 · ROD DROP
Piston and probe-gap monitoring
Rod-drop channel configurations produce average and instantaneous piston-position and probe-gap values. The physical target and reference setup determine how those values relate to the installed machine. -
03 · HYPER COMPRESSORS
High-pressure compressor position channels
The family includes a hyper-compressor channel function with displacement and gap measurements. Apply the specific channel logic and transducer fault response rather than treating it as an ordinary vibration channel.

RECIPROCATING ROD POSITION MONITOR
Integrating 3500/72M 176449-08
The monitor evaluates proximity-transducer signals for static and dynamic rod-position measurements. It compares values with alarms for reciprocating compressor monitoring. Channel functions are programmed in pairs, and the selected sensor sensitivity, target geometry and software configuration must match the measurement.
Use Rack Configuration Software 3.20 or later; Rod Position Single 2 and Pair 2 require release 6.0 or later. Standard minimum speed is 60 rpm. Operation down to 30 rpm requires modification 135M8199-01, which is not established for this stock record.
Use the matched front monitor and rear I/O in corresponding full-height rack positions. External terminations require the separately selected block and cable; they cannot be added to an internal-termination I/O. Follow the applicable channel wiring, sensor and barrier instructions before commissioning.
Features:
- Match monitor generation, matched front and rear assemblies, wiring and software
- Follow the applicable installation instructions
- Confirm unverified configuration details
The 3500/72M 176449-08 reciprocating rod position monitor requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Replacement of 3500/72M 176449-08 requires comparing monitor generation, matched front and rear assemblies, wiring and software. A shared base family or similar appearance does not establish a drop-in replacement for the complete ordered assembly.
Use Rack Configuration Software 3.20 or later; Rod Position Single 2 and Pair 2 require release 6.0 or later. Standard minimum speed is 60 rpm. Operation down to 30 rpm requires modification 135M8199-01, which is not established for this stock record.
No verified exact-order discontinuation date, product revision or designated successor is asserted. Document revisions identify the reference literature, not hardware changes to the supplied product. Unconfirmed replacement options must be resolved before substitution.
Features:
- Preserve the complete ordering identity
- Compare the installed electrical and mechanical interfaces
- Do not infer hardware revisions or successor models
The 3500/72M 176449-08 reciprocating rod position monitor requires replacement verification against the complete installed configuration and current manufacturer documentation.

How is 3500/72M 176449-08 identified?
The official spare list identifies 176449-08 as the 3500/72M Recip Rod Position Monitor. Match its front module with the specified rear I/O. The record does not establish the supplied I/O option, delivered firmware revision or a lower-speed modification. -
What is the function of this component?
The monitor evaluates proximity-transducer signals for static and dynamic rod-position measurements. It compares values with alarms for reciprocating compressor monitoring. Channel functions are programmed in pairs, and the selected sensor sensitivity, target geometry and software configuration must match the measurement. -
Which installed equipment must be matched?
Use Rack Configuration Software 3.20 or later; Rod Position Single 2 and Pair 2 require release 6.0 or later. Standard minimum speed is 60 rpm. Operation down to 30 rpm requires modification 135M8199-01, which is not established for this stock record. -
Where is this component used?
Compatible proximity transducers provide signals for the configured rod-position values. The paired channel arrangement and transducer scale factor must match the compressor installation. -
What must be checked during installation?
Use the matched front monitor and rear I/O in corresponding full-height rack positions. External terminations require the separately selected block and cable; they cannot be added to an internal-termination I/O. Follow the applicable channel wiring, sensor and barrier instructions before commissioning. -
Does every 3500/72M support a 30 rpm machine?
No. The standard lower limit is 60 rpm. The manufacturer requires modification 135M8199-01 for speeds down to 30 rpm; verify its actual presence. -
Is OK Channel Defeat enabled for rod-position and rod-drop channels?
No. The source disables it for those configurations. In a hyper-compressor configuration, both transducers becoming NOT OK cause an immediate Danger alarm; verify the complete protection configuration.
