📘 Product Introduction: Bently Nevada 3500/45 140072-02 + 140072-04
The Bently Nevada 3500/45 Position Monitor, combining components 140072-02 and 140072-04, is a four-channel machinery monitoring module designed to observe and protect rotating assets by measuring positional parameters. It is an integral part of the 3500 Series Machinery Protection System and is designed to interface with sensors such as proximity probes, Linear Variable Differential Transformers (LVDTs), rotary potentiometers, and other position-sensitive transducers.
This module provides real-time, continuous monitoring of various positional variables, including shaft axial position, valve position, differential expansion, and case expansion. It is ideally suited for critical machines where mechanical positioning, expansion, or displacement must be tightly controlled to ensure optimal performance and reliability.

❓ Product FAQ – 10 Questions & Answers (Q&A)
Q1: What does the 3500/45 module monitor?
A1: It monitors position-based parameters such as axial shaft position, differential expansion, case expansion, and valve position.
Q2: What types of sensors are supported?
A2: Proximity probes, AC/DC LVDTs, and potentiometer-based position sensors.
Q3: Can all four channels be configured differently?
A3: Yes, each of the four channels can be independently configured for different sensors and functions.
Q4: Is the 3500/45 compatible with older Bently Nevada systems?
A4: It is designed for integration into the 3500 Series rack system but is not backward-compatible with earlier series like the 3300 without significant modification.
