The BENTLY NEVADA 3500/50M is a high-performance tachometer monitor module designed for critical rotating machinery applications. As part of the 3500 Series, it supports dual-channel input from proximity probes or magnetic sensors to measure shaft speed, rotor acceleration, and rotational direction. With programmable alarm setpoints and real-time data processing, the module ensures precise condition monitoring and early fault detection. Its robust industrial design, EMI/RFI shielding, and compliance with API 670 standards make it ideal for harsh environments in oil & gas, power generation, and manufacturing.

3. Advantages and Features
Dual-Channel Redundancy: Ensures continuous monitoring even if one channel fails.
Wide Compatibility: Works with BENTLY NEVADA’s 3300XL sensors and third-party magnetic sensors.
Solid-State Design: Reduces mechanical wear and downtime compared to legacy electromechanical systems.
Real-Time Data Processing: Enables instantaneous alarm triggering and trend analysis.
Remote Configuration: Supports over-the-air updates and diagnostics via BENTLY’s 3500 组态软件.
4. Application Areas and Case Studies
Oil & Gas: Monitoring pump and compressor speeds in drilling platforms.
Power Generation: Tracking turbine rotor acceleration in thermal plants.
Manufacturing: Controlling conveyor belt speeds in automotive assembly lines.
Case Study: A North American refinery reduced unplanned shutdowns by 20% using the 3500/50M to detect overspeed conditions in centrifugal pumps, enabling predictive maintenance and cost savings.
Supporting higher speed ranges (up to 100,000 RPM vs. 50,000 RPM).
Including built-in EMI/RFI protection without external filters.
6. Selection Recommendations
System Complexity: Choose the 3500/50M for multi-axis systems requiring redundancy.
Environment: Opt for this module in high-vibration or high-temperature settings.
Integration: Pair with BENTLY’s 3500 Series framework for seamless data aggregation.
7. Precautions
Sensor Alignment: Ensure proper probe-to-target spacing (0.5–1.5 mm for eddy current sensors).
Cable Management: Use shielded cables and avoid routing near high-voltage lines.
Calibration: Perform annual checks to maintain accuracy.
