Bently Nevada 3300/25-01-00-00-00-00-03-00 Dual Accelerometer Monitor

The Bently Nevada 3300/25-01-00-00-00-00-03-00 is a high‑precision dual‑channel accelerometer monitoring module within the 3300 Series Turbine Supervisory Instrumentation (TSI) platform, designed and manufactured by Baker Hughes (formerly GE Bently Nevada). It is engineered for continuous, online monitoring of absolute vibration on machine casings, bearing housings, gearboxes and structural bases of critical rotating machinery. This unit features two independent input channels, standard signal conditioning, configurable filtering, three sealed alarm relays, comprehensive self‑diagnostics and backplane bus communication. It supports hot‑swap installation in a 19‑inch standard rack and can be mixed with other 3300 series modules. Widely deployed in power generation, oil and gas, petrochemicals, metallurgy and air separation industries, it provides early fault warning, condition assessment and safety protection for turbines, compressors, fans, pumps and other high‑value assets, fully compliant with API 670 standards.

Function & Positioning

This module functions as a core vibration monitoring and protection device for rotating machinery, focusing on mid‑to‑high frequency absolute vibration measurement. It acquires real‑time vibration data from two piezoelectric accelerometers, processes signals with fixed/selectable filtering, and provides three independent sealed relay outputs for alarm and trip logic. It supports both local panel configuration and remote setup via host systems, with adjustable alarm delays to suppress false triggering. Integrated hardware self‑diagnostics continuously monitor power, circuitry, sensor wiring and relay status, enabling fast fault localization and maintenance. As a key component of the 3300 TSI system, it seamlessly integrates with System 1 software and plant‑wide DCS/PLC/SCADA networks for data trending, storage, analysis and predictive maintenance.
