107770-02-01 | Bently Nevada | critical 4-channel Analog Vibration Monitor module

Bently Nevada is a global leader in industrial asset condition monitoring and protection, specializing in vibration, pressure, and speed measurement solutions for critical machinery. Founded in 1956 by Don E. Bently, the company pioneered eddy-current proximity probes, revolutionizing rotor dynamics monitoring. Acquired by GE in 2002, Bently Nevada operates in over 50 countries, serving industries such as oil & gas, power generation, and mining. Its product portfolio includes sensors, monitoring systems like the 3500 Series, diagnostic instruments, and predictive maintenance software such as System 1. With over 25,000 customers worldwide, the company combines more than 60 years of expertise with cloud-connected solutions to enhance asset reliability and operational safety.

The Bently Nevada 107770-02-01 is a critical 4-channel Analog Vibration Monitor module from the renowned 3500 machinery protection system. Designed for high-reliability applications, its primary function is to continuously monitor vibration levels from up to four proximity probes or seismic transducers on large rotating equipment such as turbines, compressors, pumps, and fans. The module conditions the raw sensor signals, converts them into a standardized format, and provides key vibration values (including overall amplitude and a gap voltage for proximity probes) to the system's monitoring framework for real-time analysis and protection.

This module acts as the essential data acquisition front-end within the 3500 rack. It receives power from the rack's backplane and transmits the processed analog vibration signals to other dedicated modules, such as the 3500/42M Proportional Monitor or the 3500/44M Transient Data Interface module, for further processing, alarming, and trip functions. Key features include its robust design for harsh industrial environments, high channel density which saves space in the rack, and hot-swappability, allowing for maintenance or replacement without shutting down the entire protection system.

As a fundamental component of a comprehensive machinery health monitoring solution, the 107770-02-01 helps prevent catastrophic failures by enabling the early detection of abnormal vibration conditions. Its integration into the Bently Nevada 3500 system ensures operational reliability, safety, and predictive maintenance capabilities in critical industries such as oil and gas, power generation, and petrochemicals.
