The 3500/40M (176449-01) is widely deployed in mission-critical machinery monitoring systems where precise shaft movement detection is required. Typical applications include shaft centerline position measurement, reciprocating compressor rod drop monitoring, and axial thrust displacement detection for turbines, compressors, and large electric motor-driven equipment. These capabilities enable early fault detection and prevent costly equipment failures in industries such as power generation, oil & gas, and petrochemical processing.
What is the primary function of the 176449-01 module?
The module conditions signals from proximity probes and converts them into accurate vibration and position data used by the 3500 system for machine monitoring and automatic protection functions.
Does this module support legacy proximity probes?
Yes. The 3500/40M is designed to maintain compatibility with most standard Bently Nevada eddy-current proximity transducer systems, including earlier probe models.
How are alarm thresholds configured?
Alarm setpoints are configured through the 3500 Rack Configuration Software via the rack’s system interface module, allowing engineers to define alert and danger thresholds based on machine operating parameters.
