Bentley Nevada

The Bently Nevada 330850-51-00 is a high-performance Proximitor® sensor from the 3300 XL 25 mm proximity transducer system series. This signal conditioning unit serves as the interface between a 25 mm eddy current proximity probe and your machinery monitoring system, converting raw probe signals into a precise, linear voltage output proportional to the distance between the probe tip and the target surface . Unlike standard 8 mm systems with limited range, the 25 mm system is specifically engineered for long-range displacement measurements required in large rotating machinery applications such as steam turbines, axial compressors, and generators.

The Bently Nevada 330881-16-00-115-01-02 is a PROXPAC XL Proximity Transducer, an integrated, self-contained proximity probe system that combines the probe, extension cable, and Proximitor® sensor into a single, factory-matched assembly . Unlike traditional separate-component systems, this design eliminates the need for a separate extension cable between the probe and its associated Proximitor sensor, simplifying installation and improving system reliability . The "PROXPAC XL" housing is made of Polyphenylene Sulfide (PPS), a durable molded thermoplastic that replaces the steel and aluminum used in earlier housings. The material incorporates glass and conductive fibers to strengthen the housing and effectively dissipate electrostatic charges . This assembly is designed for non-contact vibration and displacement monitoring of rotating machinery such as turbines, compressors, pumps, and generator.

The Bently Nevada 3500/91-01-01-00 is an EGD (Ethernet Global Data) Communication Gateway Module designed for the 3500 Machinery Protection System . It serves as the primary data bridge between the 3500 rack and external control systems such as Distributed Control Systems (DCS), Plant Information Management Systems (PIMS), and GE Mark* VIe turbine controllers. This module provides comprehensive communication capabilities for 3500 rack-monitored values and status over an Ethernet network path, delivering information with response times suitable for controller applications . It occupies one full-height front slot and one full-height rear I/O slot in the 3500 rack.

The Bently Nevada 3500/42 135489-01 is a 4-channel I/O module designed specifically for the 3500/42M Proximitor®/Seismic Monitor, part of the industry-standard 3500 Machinery Protection System . This module serves as the critical interface between field sensors and the monitoring system, accepting inputs from proximity probes, seismic transducers, and accelerometers. The 135489-01 variant features internal safety barriers and internal terminations, making it the ideal choice for hazardous area installations . By integrating intrinsic safety circuitry directly onto the I/O board, this module eliminates the need for external Zener barriers or isolators, simplifying wiring, saving panel space, and reducing potential failure points.

The Bently Nevada 3500/40 135489-04 is a 4-channel Proximitor® displacement monitor, part of the industry-standard 3500 Machinery Protection System . It accepts inputs from non-contacting eddy current proximity probes, conditions the signals to provide vibration and position measurements, and compares them against user-programmable alarms to protect critical rotating machinery . This specific variant (135489-04) is an I/O module featuring internal safety barriers and internal terminals, eliminating the need for external Zener barriers or isolators in hazardous areas . It is engineered to meet API 670 standards for machinery protection , providing the first line of defense for turbines, compressors, and other high-value assets.
