Application & Failure Scenarios
Where this spare becomes relevantThe 3500/70M is designed for reciprocating compressor monitoring, including crankcase and crosshead vibration measurement. It uses seismic-transducer inputs to provide vibration measurements for machinery-protection applications.
The 176449-09 is relevant when an installed 3500/70M monitor requires replacement, troubleshooting, or restoration of the configured vibration-monitoring function.
Shutdown risk
Loss of the applicable monitoring function may reduce the availability of vibration information used for machinery protection, operation, and maintenance decisions. The actual impact depends on the machine’s protection architecture and configured alarm strategy.
