The Bently Nevada 330780-51-05 is a high-performance Proximitor® sensor from the 3300 XL series, specifically engineered to function as the signal conditioner and amplifier within a complete 11 mm proximity transducer system . As the critical link between the 11 mm eddy current proximity probe and your monitoring system (such as the 3500/42M), this sensor powers the probe, processes the raw gap voltage signal, and outputs a precise, high-level signal proportional to the distance between the probe tip and the target shaft .   Designed for non-contacting vibration and displacement measurements on fluid film bearing machines, this module is an ideal solution for modernizing legacy monitoring infrastructure, particularly as a seamless upgrade for outdated 7200-series transducer systems . Its advanced design ensures superior reliability and is a cornerstone component for building robust machinery protection systems in the most demanding industrial environments .   The specific model 330780-51-05 is configured as a 5.0-meter total system length unit with a DIN-rail mount and multiple international agency approvals.

The Bently Nevada 330180-91-05 is a 3300 XL Proximitor Sensor, the signal conditioning module for the 3300 XL 8 mm Proximity Transducer System. Its core function is to supply radio-frequency power to an eddy-current proximity probe, receive the modulated signal from the probe, and convert the measured gap into a linear DC voltage output directly proportional to the distance between the probe tip and a conductive rotating shaft. This enables precise measurement of radial vibration, axial position, and speed for critical machinery protection.

The Bently Nevada 330180-50-05 is a 3300 XL Proximitor Sensor, a signal conditioning module for the 3300 XL 8 mm Proximity Transducer System. Its core function is to supply radio-frequency power to an eddy-current proximity probe, receive the modulated signal from the probe, and convert the measured gap into a linear DC voltage output for machinery monitoring systems. This output is directly proportional to the distance between the probe tip and a conductive rotating shaft, enabling precise measurement of radial vibration, axial position, and speed.

The Bently Nevada 127610-01 is an AC power supply module (model 3500/15) for the 3500 Series Machinery Protection System. Its core function is to convert an AC input voltage into the stable DC power required by all other modules in a 3500 monitoring rack. It provides an isolated, regulated DC output (typically +5 V, +15 V, and +24 V) to power the entire backplane, ensuring the uninterrupted operation of critical machinery monitoring system.

The Bently Nevada 288055-01 is the 3500/22M Standard Transient Data Interface (TDI) Module, a critical component of the 3500 Series Machinery Protection System. It serves as the primary communication gateway and data acquisition interface between the 3500 monitoring system and external machinery management software such as GE's System 1* . The TDI collects both steady-state and transient waveform data from the 3500 rack's monitoring modules (including vibration, position, and temperature monitors) and transmits it via high-speed Ethernet for analysis and diagnostics. Importantly, it operates independently of the critical monitoring path, ensuring that machinery protection functions continue uninterrupted even if the TDI loses communication.

The Bently Nevada 3500/53-03-00 is a highly reliable Electronic Overspeed Detection System designed for the 3500 Series Machinery Protection System. This module provides critical overspeed protection for rotating machinery such as steam and gas turbines, compressors, generators, and turbo-expanders by continuously monitoring rotational speed and initiating a trip signal when preset limits are exceeded. The -03-00 configuration indicates a Three-Channel System with no additional agency approvals. This triple-redundant architecture enables voting logic configurations (2-out-of-2 or 2-out-of-3) to prevent false trips while ensuring genuine overspeed events are reliably detected.

The Bently Nevada 3500/32 125720-01 is the I/O termination module that completes the 3500/32 4-Channel Relay Module system. Together with the 149986-02 (or 125712-01) main logic board, this assembly provides four independent, programmable relay outputs that serve as the critical link between the 3500 monitoring system and external control devices . As a full-height module designed for the 3500 Series Machinery Protection System, it translates alarm logic states—such as Alert, Danger, or Not OK conditions—from monitoring modules into physical dry contact outputs. These contacts can directly drive alarm indicators, sirens, machine trip circuits, or PLC/DCS inputs, making it an essential component for hard-wired machinery protection and automated control applications in turbines, compressors, and generators.

The Bently Nevada 3500/25 149369-01 is a half-height, two-channel Enhanced Keyphasor Module for the 3500 Series Machinery Protection System. Its core function is to receive input signals from proximity probes or magnetic pickups and convert them into precise digital Keyphasor signals. These signals indicate exactly when a Keyphasor mark on a rotating shaft passes the sensor, providing a critical timing reference used to measure rotational speed, vibration phase, and other vector parameters.

The Bently Nevada 3500/22M 138607-01 is a Transient Data Interface (TDI) module for the 3500 Series Machinery Protection System. Its core function is to serve as the primary communication bridge between the 3500 monitoring rack and upper-level software, such as System 1® machinery management software and 3500 System Configuration software. It combines the functionality of the earlier 3500/20 Rack Interface Module (RIM) and a communication processor like TDXnet, consolidating data acquisition and system interface tasks into a single module.

The Bently Nevada 3500/22M-01-01-00 is a Transient Data Interface (TDI) module for the 3500 Series Machinery Protection System. Its core function is to serve as the primary communication bridge between the 3500 monitoring rack and upper-level software, such as System 1 machinery management software and 3500 System Configuration software. By combining the functionality of the earlier 3500/20 Rack Interface Module (RIM) and a communication processor like TDXnet, it consolidates data acquisition and system interface tasks into a single module.

The Bently Nevada 3500/42M-01-00 is a four-channel Proximitor Seismic Monitor from the 3500 Series Machinery Protection System. Its core function is to continuously monitor the vibration and position of critical rotating machinery by accepting inputs from proximity and seismic transducers. It conditions these signals and compares them against user-programmable alarms to provide essential protection and status information.

The Bently Nevada 3500/94 is a dedicated VGA Display Router and Human-Machine Interface (HMI) module for the 3500 Machinery Protection System. It provides a high-fidelity visual interface, allowing operators to view real-time machinery data, alarm event lists, and system status directly at the rack or from a remote terminal . This module acts as the central visualization hub, translating complex machinery data from the 3500 rack into intuitive graphics, bar graphs, and alarm lists on a standard color VGA monitor.
