3500/40 is a Proximitor Monitor I/O Module manufactured and designed by Bently Nevada as part of the 3500 Series used to control the machinery condition monitoring system. The GE / Bently Nevada 3500/40 Series Proximitor Monitors are 4-channel monitors that accept input from proximity transducers made by Bently Nevada, condition the signal to produce different vibration and position measures, and compare the conditioned signals with user-programmable alarms. The Radial Vibration, Thrust Position, Differential Expansion, Eccentricity, and REBAM functions can all be programmed into each channel of the 3500/40 using the 3500 Rack Configuration Software. The Proximitor Monitor I/O Module is designed to provide the necessary inputs and outputs for connecting proximity probes and monitoring their signals. It typically includes multiple channels to accommodate multiple probes and can interface with various types of proximity probes, such as eddy current probes and capacitive probes.


The features of a Proximitor Monitor I/O Module can vary depending on the specific model and manufacturer. However, here are some common features that you may find in such a module:

Proximity Probe Inputs: The module typically provides multiple channels for connecting proximity probes. These inputs are designed to accommodate different types of probes, such as eddy current probes and capacitive probes.

Signal Conditioning: The module includes signal conditioning circuits to amplify, filter, and process the signals from the proximity probes. This ensures accurate and reliable measurements of vibration and position.

Measurement Parameters: The module may offer various measurement parameters, such as displacement, velocity, and acceleration, depending on the type of proximity probes being used. It allows for monitoring different aspects of machinery performance.

Digital and Analog Outputs: The module provides both digital and analog outputs to interface with monitoring systems or control devices. Digital outputs may include relays or discrete alarms for triggering alerts or shutdowns based on predefined thresholds. Analog outputs can provide continuous voltage or current signals representing the measured parameters.

Communication Interfaces: Some Proximitor Monitor I/O Modules may include communication interfaces, such as RS-485, Ethernet, or Modbus, allowing for remote monitoring and integration with a larger control or data acquisition system.

What is the purpose of a Proximitor Monitor I/O Module?

The Proximitor Monitor I/O Module is used to monitor and interface with proximity probes, which are sensors used to measure the distance, vibration, and position of rotating machinery. The module provides inputs for connecting proximity probes, signal conditioning circuits to process the probe signals, and outputs for transmitting the processed signals to monitoring systems or control devices.

What types of proximity probes can be used with a Proximitor Monitor I/O Module?

The module is designed to work with various types of proximity probes, including eddy current probes and capacitive probes. It can accommodate different probe sizes and configurations, allowing for flexibility in monitoring different types of machinery.

Can a Proximitor Monitor I/O Module provide real-time monitoring?

Yes, the module is designed to provide real-time monitoring of proximity probe measurements. It continuously processes the signals from the probes and outputs the measured parameters, such as displacement or velocity, in real time. This allows for the immediate detection of any abnormalities or changes in the machinery's performance.
