The Bently Nevada 330101-00-40-05-02-00 is a non-contact proximity transducer system from the 3300 XL 8 mm series, designed for precision vibration and position measurement in critical rotating machinery. Its core function is to provide a linear output voltage that is directly proportional to the distance between the probe tip and a conductive target, such as a rotating shaft. This measurement is essential for machinery protection and predictive maintenance, enabling the detection of unbalance, misalignment, and bearing wear before they cause catastrophic failure. The system's advanced design offers high performance, interchangeability, and compliance with international standards.

The Bently Nevada 177230-02-01-CN is a loop-powered velocity vibration transmitter for the 177230 series . Its core function is to convert mechanical vibration velocity on a machine's bearing housing or casing into a standard 4-20 mA signal, proportional to the vibration level for continuous monitoring and integration with control systems.

The Bently Nevada 330106-05-30-05-02-05 is a component of the 3300 XL 8 mm Proximity Transducer System. Its core function is to serve as an extension cable, providing a reliable electrical connection between a reverse mount proximity probe and a Proximitor sensor. This cable ensures the transmission of high-fidelity signals for vibration and position monitoring. In the 3300 XL system, the probe and the Proximitor sensor are precision-matched to a specific electrical length. The total electrical length of the probe plus the extension cable must match that of the Proximitor for accurate measurements .

The Bently Nevada 3500/45 176449-04 is a high-performance 4-channel position monitor from the 3500 Series machinery protection system. This module is designed to accept inputs from a wide variety of position transducers — including proximity probes, Rotary Position Transducers (RPTs), DC/AC LVDTs, and rotary potentiometers — and provide continuous, real‑time monitoring of critical position parameters.   The 176449-04 is a main board module that must be paired with a compatible I/O module (e.g., 135137-01 for internal terminations) to form a complete position monitoring solution. It is widely deployed in power generation, oil & gas, and heavy industrial facilities for monitoring turbines, compressors, and other large rotating machinery.

The Bently Nevada 3500/33 149992-01 is a full-height, 16-channel relay output module for the 3500 Series Machinery Protection System. Its core function is to serve as the system's "executor," converting alarm and status signals from monitor modules (e.g., vibration, position, speed monitors) into physical relay contact outputs. These outputs are used to trigger alarms, activate emergency shutdown sequences, or control external equipment, ensuring reliable protection actions even if the upper-level control system fails.

The Bently Nevada 330104-00-05-10-01-00 is an 8 mm proximity probe from the 3300 XL series, forming part of a high-performance eddy-current transducer system. Its core function is to provide non-contact, high-precision measurements of shaft vibration and position for critical rotating machinery, such as turbines, compressors, and pumps. It converts mechanical motion into a stable, linear voltage signal proportional to the gap between the probe tip and the target surface.

The Bently Nevada 3500/25-01-03-00 is an Enhanced Keyphasor Module designed for the 3500 Machinery Protection System. This half-height, two‑channel module processes signals from eddy‑current proximity probes or magnetic pickups, converting them into digital phase reference pulses. These pulses indicate precisely when a shaft's Keyphasor mark passes the transducer, providing the critical timing reference required for accurate vibration monitoring and shaft speed measurement .   This specific configuration –01‑03‑00 includes a single half‑height two‑channel Keyphasor card, an Internal Barrier I/O module with internal terminations for safe wiring in hazardous areas, and no external agency approvals . As an upgraded replacement for the legacy 125792‑01 module, it offers expanded processing capabilities while maintaining complete backward compatibility.

The Bently Nevada 136188-02 is the I/O module for the 3500/92 Communication Gateway, serving as the physical interface that connects the 3500 machinery protection system to plant-wide automation networks. This module provides the physical termination points for both Ethernet and serial communication, enabling data exchange between the 3500 rack and external systems such as DCS, PLC, and SCADA platforms .   As an integral part of the 3500/92 system (paired with the 136180-01 main board), this module converts monitored vibration, temperature, and position data into industry-standard Modbus formats for seamless system integration . The specific configuration 136188-02 indicates an Ethernet/RS485 Modbus I/O module.

The Bently Nevada 330780-50-00 is a high-performance Proximitor® sensor from the 3300 XL 11 mm proximity transducer system series.
