The BENTLY 330980-51-00 is a highly specialized and sensitive vibration transducer, specifically a Proximity Probe, designed for the continuous monitoring of rotating and reciprocating machinery. This device is a critical component in predictive maintenance and machinery protection systems, providing direct measurement of shaft relative displacement (position), vibration, and phase reference. The BENTLY 330980-51-00 probe system typically includes the probe itself, an extension cable, and a driver (oscillator/demodulator) module. It operates on the eddy current principle, where the probe generates an electromagnetic field, and changes in the gap between the probe tip and the conductive target (usually the machine shaft) are converted into a precise DC voltage proportional to distance. The reliability and accuracy of the BENTLY 330980-51-00 are paramount for detecting issues like shaft misalignment, imbalance, bearing wear, and oil whirl in turbomachinery such as compressors, turbines, and large pumps.

This module, part of a larger system like the classic 3300 or 3500 series, serves as the foundational hub for a rack or enclosure. The BENTLY 125768-01 performs two essential functions: it converts incoming AC or DC plant power to the clean, regulated DC voltages required by all the monitoring modules (vibration, position, speed) in the rack, and it provides the primary communication interface between the rack and the plant’s Distributed Control System (DCS) or PLC. It is the module that powers the system and facilitates the transmission of alarm, trip, and analog trend data to the control room.
Product Description
The BENTLY 135489-03 is a Proximitor® Power Supply and Signal Conditioner, a critical component in machinery monitoring and protection systems from Bently Nevada (now part of Baker Hughes). This unit is not a PLC module but a specialized electronic device that provides the necessary power and signal conditioning for eddy current proximity probes (transducers) used to measure shaft vibration, displacement (position), and speed. The primary function of the BENTLY 135489-03 is to supply a high-frequency radio frequency (RF) excitation signal to the proximity probe and to convert the probe’s raw signal into clean, standardized voltage outputs (e.g., -1 to -20 Vdc for gap, and 0 to 1 Vpk for vibration) that can be safely read by monitoring systems like the Bently Nevada 3500, 3300 series, or other data acquisition systems.
