​1. Product Overview and Core Functionality​

The Bently Nevada 3500/44M is a high-performance, quad-channel vibration monitoring module within the 3500 Machinery Protection System, designed for safeguarding critical industrial machinery. This module specializes in processing vibration signals from accelerometers or velocity sensors to detect mechanical anomalies such as imbalance, misalignment, bearing wear, and resonance in rotating equipment. It supports dynamic acceleration, velocity, or displacement measurements with configurable frequency ranges (e.g., 10 Hz to 1 kHz or 1 kHz to 10 kHz) to align with specific machinery requirements. Built for harsh environments, the 3500/44M operates reliably across a temperature range of -40°C to 85°C and complies with API 670 standards for machinery protection. Its modular design integrates seamlessly into the 3500 series framework, providing 4-20 mA outputs and relay alarms for real-time condition monitoring and control system integration.

​2. Technical Specifications and Advanced Features​

The 3500/44M offers precise vibration analysis with adjustable bandpass filtering, alarm thresholds, and self-diagnostic capabilities. Each of its four channels supports input sensitivities up to 500 mV/g and delivers 24 VDC loop power to sensors, reducing external wiring complexity. The module is certified for hazardous areas (ATEX/IECEx) and features an IP52 enclosure rating for dust and moisture resistance. Integration with Bently Nevada’s System 1™ software enables advanced diagnostics, trend analysis, and predictive maintenance insights. Its hot-swappable design and DIN rail mounting ensure minimal downtime during maintenance, while redundant communication ports enhance system reliability in power plants, oil refineries, and chemical processing facilities.

​3. Applications and Operational Excellence​

Widely deployed in energy, manufacturing, and petrochemical industries, the 3500/44M plays a pivotal role in protecting turbines, compressors, and pumps from catastrophic failures. By delivering continuous vibration data, it enables early fault detection, reducing unplanned downtime and maintenance costs. The module’s compatibility with legacy and modern control systems simplifies upgrades, while its scalable architecture supports expanding monitoring needs. Fail-safe relay logic and event-triggered data capture ensure rapid response to abnormal conditions, enhancing operational safety and equipment longevity. Trusted globally, the 3500/44M exemplifies Bently Nevada’s commitment to precision, durability, and innovation in industrial automation solutions.
