Functional Description

The Bently Nevada 3500/45 is a 4-channel Position Monitor Module designed for machinery protection and condition monitoring. It processes input signals from various sensors, including:

Proximity transducers

Rotary Position Transducers (RPTs)

DC & AC Linear Variable Differential Transformers (LVDTs)

Rotary potentiometers

Each channel can be configured via 3500 Rack Configuration Software to support multiple monitoring functions, such as:

Axial (Thrust) Position

Differential Expansion (Standard, Non-standard, Dual Ramp, Complementary)

Case Expansion

Valve Position

The module continuously compares sensor inputs against user-programmable alarm setpoints, triggering alerts when thresholds are exceeded. This ensures early detection of potential machinery failures, providing critical data for maintenance and operational decisions.

Key Features

✅ Real-Time Monitoring – Tracks channel positions continuously for immediate feedback.

✅ Programmable Alarms – Configurable alert and danger setpoints for each channel.

✅ Historical Data Logging – Stores trend data for analysis and diagnostics.

✅ Remote Access & Integration – Compatible with control systems for seamless monitoring.

✅ User-Friendly Interface – Easy configuration via dedicated software.

✅ High Reliability – Operates in harsh environments (-30°C to +65°C).

✅ Scalability – Supports expansion for additional monitoring needs.
