3500/45 is a Channel Position Monitor Module manufactured and designed by Bently Nevada as part of the 3500 Series used for monitoring seismic activity. The 3500/45 Position Monitor is a 4-channel instrument that accepts input from 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 the input and compares the conditioned signals with user-programmable alarms. You can program each channel using the 3500 Rack Configuration Software to perform the following functions:

  • 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

The primary purpose of the 3500/45 Position Monitor is to provide the following:

  • Machinery protection by continuously comparing monitored parameters against configured alarm setpoints to drive alarms.
  • Essential machine information for operations and maintenance personnel Each channel, depending on configuration, typically conditions its input signal to generate various parameters called measured variables.
  • You can establish alert setpoints for each active measured variable and danger setpoints for any two of the active measured variables.


Real-time Monitoring: The module may provide real-time monitoring of channel positions or statuses. This allows users to have up-to-the-minute information on the location or status of various channels.

User Interface: An intuitive user interface could be a key feature. This would make it easy for users to navigate and understand the information presented by the module.

Alerts and Notifications: The ability to set up alerts and notifications is crucial. Users may want to be notified when a channel reaches a specific position or encounters a particular condition.

Historical Data Logging: Storing historical data allows users to track channel positions over time. This feature can be valuable for analysis, troubleshooting, and decision-making.

Compatibility: The module should be compatible with the systems or equipment it is monitoring. This could involve integration with other control systems or communication protocols.

Remote Access: The ability to monitor channels remotely is often essential. This feature enables users to check channel positions or statuses from a distance, which can be critical in various applications.

Customization: The module may offer customization options to tailor its functionality to specific user needs. This could include setting parameters, adjusting alert thresholds, or configuring the display.

Security: Security features are crucial to protect the data and ensure that only authorized individuals can access or modify channel position information.

Scalability: The module should be scalable to accommodate changes in the number of channels being monitored. This ensures flexibility as system requirements evolve.

Diagnostic Tools: The inclusion of diagnostic tools can be beneficial for troubleshooting and identifying issues with channel positions.

Integration with Control Systems: For applications where channel positions are part of a larger control system, seamless integration with these systems is essential.
