3500/33-01-00 multi-function monitor module

The 3500/33-01-00 is a multi-function monitor module launched by Bently Nevada, a core component of the 3500 Series machinery protection system. It is mainly used for comprehensive condition monitoring and fault early warning of large rotating machinery, with strong compatibility and reliable protection performance. Below is its detailed information:

1. Basic Information

Brand: Bently Nevada
Model: 3500/33-01-00
Product Type: Multi-function Monitor Module (belonging to the 3500 Series machinery protection system)
Typical Matching Components: Compatible with Bently Nevada’s standard 3500 system frame, and usually used with eddy current proximity probes, velocity sensors, or acceleration sensors (depending on monitoring needs).

2. Core Functional Features

As a multi-function module, it integrates multiple monitoring and protection capabilities, focusing on meeting the comprehensive detection needs of rotating machinery:

Multi-parameter Monitoring: Supports simultaneous monitoring of multiple key mechanical parameters, including radial vibration, axial thrust position, differential expansion, and eccentricity (for startup/shutdown processes). It can process signals from different types of sensors to adapt to diverse application scenarios.
Dual-channel Independent Operation: Equipped with 2 independent monitoring channels, each channel can be configured with separate sensor inputs, alarm thresholds, and output logic. This design ensures that failures in one channel do not affect the operation of the other, improving system reliability.
Programmable Alarm & Trip Logic: Users can set warning alarms and danger trip thresholds for each parameter through the 3500 system configuration software (e.g., System 1 software). When parameters exceed the set values, the module triggers visual (LED indicators) and electrical (relay/output signals) alerts, and can link to the machine’s emergency shutdown system if needed.
Signal Conditioning & Filtering: Built-in high-precision signal conditioning circuits, which can amplify, filter, and linearize the weak signals collected by sensors (e.g., eddy current probe signals). It effectively suppresses electromagnetic interference (EMI) and noise, ensuring the accuracy of measurement data.
Backward Compatibility: Fully compatible with earlier versions of 3500 series modules in terms of form factor, electrical interface, and communication protocol. It can be directly replaced or added to existing 3500 system frames without modifying the overall system structure.
