Bently Nevada 135137-01 Host Communication Module

The 3500/45 135137-01 Position Monitor is a 4-channel monitoring device designed to accept inputs from various transducers, such as proximity transducers, Rotary Position Transducers (RPTs), DC Linear Variable Differential Transformers (DC LVDTs), AC Linear Variable Differential Transformers (AC LVDTs), and rotary potentiometers. The monitor conditions these inputs and compares the signals with user-programmable alarms. Here are some key features and functionalities:

1. Input Compatibility:
   • Accepts input from proximity transducers, RPTs, DC LVDTs, AC LVDTs, and rotary potentiometers.
2. Functionality and Configuration:
   • The 3500 Configuration Software can program each channel of the 3500/45 to perform various functions, including:
     • Axial (thrust) Position
     • Differential Expansion
     • Standard Single Ramp Differential Expansion
     • Non-standard Single Ramp Differential Expansion
     • Dual Ramp Differential Expansion
     • Complementary Differential Expansion
     • Case Expansion
     • Valve Position
3. Channel Pairing and Functions:
   • The monitor channels are programmed in pairs, and each pair can perform up to two of the mentioned functions simultaneously.
   • Channels 1 and 2 can perform one function, while channels 3 and 4 can perform another (or the same) function.
   • Channels 3 and 4 are specifically mentioned as being able to perform Case Expansion.
4. Proportional Values:
   • Each channel conditions its input signal into various parameters referred to as “proportional values.”
5. Alarm Configuration:
   • User-programmable alarm setpoints are used to continuously compare monitored parameters, driving alarms when necessary.
6. Machinery Protection:
   • The primary purpose of the 3500/45 135137-01 monitor is to provide machinery protection by continuously monitoring parameters and triggering alarms based on configured setpoints.
7. Information for Personnel:
   • It also serves to provide essential machine information for both operations and maintenance personnel.
8. Alert and Danger Setpoints:
   • Alert setpoints can be configured for each active proportional value.
   • Danger setpoints can be configured for any two of the active proportional values.

In summary, the 3500/45 135137-01 Position Monitor is a versatile monitoring solution designed for machinery protection and providing valuable information to operations and maintenance personnel by monitoring various parameters and triggering alarms based on user-configurable setpoints.
