PRODUCT DESCRIPTION
Reciprocating compressor vibration monitor
Bently Nevada 3500/70M 176449-09 is a reciprocating vibration monitor. The monitor evaluates seismic-transducer signals for reciprocating compressor crankcase and crosshead vibration. Available functions include impulse acceleration, acceleration and reciprocating velocity. Channels are configured in pairs and compared with programmed alarms, with the chosen measurement and sensor arrangement determining valid results.
The official spare table identifies 176449-09 as the 3500/70M Recip Impulse Velocity Monitor. Match the rear I/O, transducer and configuration to the installed compressor. The supplied part number does not establish its firmware or the presence of a low-speed modification.

ACTUAL APPLICATIONS
Applications for 3500 reciprocating vibration 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 · CRANKCASE VIBRATION
Compressor-frame condition monitoring
The manufacturer describes crankcase vibration monitoring as part of the reciprocating compressor solution. Select the seismic transducer and channel function suitable for that physical location. -
02 · CROSSHEAD VIBRATION
Impulse-related compressor measurements
Impulse-acceleration channels can evaluate peak or RMS acceleration within selected crank-angle bands. These measurements depend on the configured compressor timing and supported operating speed. -
03 · LOW-FREQUENCY VELOCITY
Reciprocating machine vibration trends
The low-frequency velocity function provides the specified filtering for appropriate reciprocating-machine measurements. Its existence does not remove the separate minimum-speed and modification requirements.

RECIPROCATING COMPRESSOR VIBRATION MONITOR
Integrating 3500/70M 176449-09
The monitor evaluates seismic-transducer signals for reciprocating compressor crankcase and crosshead vibration. Available functions include impulse acceleration, acceleration and reciprocating velocity. Channels are configured in pairs and compared with programmed alarms, with the chosen measurement and sensor arrangement determining valid results.
The current source specifies Rack Configuration 5.2, monitor firmware 4.21 and System 1 version 6.90 or later, with corresponding TDI firmware requirements. Standard minimum speed is 60 rpm; modification 135M8137-01 is required for operation down to 30 rpm.
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 3500/70M 176449-09 reciprocating vibration monitor requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Replacement of 3500/70M 176449-09 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.
The current source specifies Rack Configuration 5.2, monitor firmware 4.21 and System 1 version 6.90 or later, with corresponding TDI firmware requirements. Standard minimum speed is 60 rpm; modification 135M8137-01 is required for operation down to 30 rpm.
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 3500/70M 176449-09 reciprocating vibration monitor requires replacement verification against the complete installed configuration and current manufacturer documentation.

How is 3500/70M 176449-09 identified?
The official spare table identifies 176449-09 as the 3500/70M Recip Impulse Velocity Monitor. Match the rear I/O, transducer and configuration to the installed compressor. The supplied part number does not establish its firmware or the presence of a low-speed modification. -
What is the function of this component?
The monitor evaluates seismic-transducer signals for reciprocating compressor crankcase and crosshead vibration. Available functions include impulse acceleration, acceleration and reciprocating velocity. Channels are configured in pairs and compared with programmed alarms, with the chosen measurement and sensor arrangement determining valid results. -
Which installed equipment must be matched?
The current source specifies Rack Configuration 5.2, monitor firmware 4.21 and System 1 version 6.90 or later, with corresponding TDI firmware requirements. Standard minimum speed is 60 rpm; modification 135M8137-01 is required for operation down to 30 rpm. -
Where is this component used?

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. -
Is bias voltage itself a machinery-condition measurement?
No. The manufacturer identifies it as a monitor-system diagnostic value, not information about the condition of the monitored machinery. -
Can all four channels use different monitoring functions?
The functions are programmed in channel pairs. Channels 1-2 can use one function and channels 3-4 another or the same function, providing up to two functions at once.
