1. Basic Info / Brand / Series
-
Brand: Bently Nevada
-
Series / Family: 3500 Machinery Protection / Monitoring System
-
Model / Part Numbers: 3500/04 comprising 136719‑01 + 138527‑01 (dual / paired module assembly)
-
Type: Monitor / signal processing module (vibration/displacement / protection module)
-
Role: This module provides vibration / process monitoring, data acquisition, signal conditioning, and protection logic for rotating machinery in the 3500 rack system
2. Product Introduction
The 3500/04 (136719‑01 + 138527‑01) module is part of the Bently Nevada 3500 family, designed to monitor vibration, speed, interference, and other diagnostic signals in rotating machinery. In the 3500 architecture, the 3500/04 unit typically pairs hardware (two submodules) to manage displacement, velocity, or vibration channels. It acquires signals from proximity probes, sensors, processes them, applies protection thresholds, and issues alarms or trip signals.
The dual‑part assembly (136719‑01 + 138527‑01) suggests that one part may serve as the core signal module and the other as a companion or extension (e.g. for redundancy or additional channels). Together, they integrate into the 3500 rack, connect via the backplane and communicate with other modules via the 3500 bus / backplane. The module is built for continuous, online operation in industrial environments to protect high‑value rotating equipment from damage or failure.
3. Applications
Typical applications include:
-
Machinery protection for turbines, compressors, pumps, generators
-
Monitoring bearing vibration, shaft displacement, speed
-
Detecting faults like unbalance, misalignment, rub, looseness, gear mesh anomalies
-
Issuing protective actions, alarms, and trip commands
-
Use in petrochemical, power generation, oil & gas, marine, process industries
-
Retrofit or expansion in 3500 rack systems where additional channels or redundancy are needed
4. Advantages / Strengths
Some notable strengths:
-
Proven reliability — 3500 modules are field‑tested and trusted in critical machinery environments
-
Modular design — easy to replace or expand channels without full system overhaul
-
High sensitivity and accuracy — captures fine vibration / displacement signals
-
Redundancy support — can be used in redundant architectures for high availability
-
Seamless integration with other 3500 modules (power, rack, relay, communication)
-
Real-time protection — triggers alarms or trips quickly upon fault detection
-
Diagnostic capabilities — supports trend logging and health monitoring
-
Industry standard — widely accepted in machinery protection and vibration communities
-
Scalable — supports scaling up by adding more modules
-
Support ecosystem — integration with higher-level condition monitoring and SCADA systems
