PRODUCT DESCRIPTION
3500/70M 176449-09 3500/70M Recip Impulse Velocity Monitor
Bently Nevada 3500/70M 176449-09 is a four-channel Recip Impulse Velocity Monitor for the 3500 machinery protection system. It monitors seismic vibration at reciprocating-compressor crankcase and crosshead locations for continuous mechanical-condition protection.
The full-height rack module accepts proximity or seismic transducer inputs, conditions each channel and evaluates the configured velocity measurements against programmed alarm limits. It provides 4 to 20 mA per channel recorder outputs, buffered transducer connections and paired channel programming while consuming 7.7 W nominal.

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.
