BENTLY 3500/62 Dual Channel Acceleration/Velocity Monitoring Module
Product Overview
The BENTLY 3500/62 is a high-precision Dual Channel Acceleration/Velocity Monitoring Module designed as a core component of Bently Nevada’s 3500 Series Machinery Protection System. Engineered to monitor vibration parameters in critical rotating equipment, this module converts acceleration and velocity signals from piezoelectric sensors into actionable data for predictive maintenance. As part of the 3500 Series, the 3500/62 supports seamless integration with other 3500 modules (e.g., proximity probes, keyphasor units), delivering comprehensive machinery health analysis in industries such as oil & gas, power generation, and manufacturing.
Featuring a rugged industrial design, the BENTLY 3500/62 processes vibration data from two independent channels, each supporting acceleration (0–50 g) or velocity (0–100 in/sec) measurements with ±1% accuracy. Its advanced signal conditioning circuitry includes anti-aliasing filters and built-in diagnostics, enabling real-time detection of mechanical issues like imbalance, misalignment, or bearing wear. The module’s hot-swappable architecture allows replacement without system shutdown, while its wide operating temperature range (-40°C to +70°C) ensures reliability in harsh environments. Compatibility with API 670 and IEC 61511 standards makes the 3500/62 indispensable for safety-critical applications where equipment failure risks operational downtime or hazards.
In automation ecosystems, the 3500/62 serves as the backbone of vibration monitoring systems, feeding real-time data to supervisory control layers for trend analysis and alarm activation. Its dual-channel design supports redundant sensor configurations, eliminating single points of failure. By providing precise vibration insights, the 3500/62 empowers maintenance teams to schedule proactive repairs, extend equipment lifespan, and optimize operational efficiency in mission-critical setups.
