Description
BENTLY NEVADA 3500/53 133388-01 Overspeed Detection Module
The
BENTLY NEVADA 3500/53 133388-01 is a high-precision overspeed detection module designed for critical rotating machinery in industrial environments. As part of the
3500 Series, it monitors shaft speed and acceleration using dual-channel inputs from proximity probes or magnetic sensors. The module features programmable trip points, real-time data analysis, and fault memory to prevent catastrophic failures in applications like turbines, compressors, and pumps. Its rugged design, EMI/RFI immunity, and compliance with API 670 standards make it ideal for oil & gas, power generation, and manufacturing sectors.

- Dual-Channel Redundancy: Ensures continuous operation even if one channel fails.
- Fast Response Time: Detects overspeed conditions in <50 ms for rapid shutdown.
- Rate-of-Speed Rise (ROR) Detection: Identifies accelerating failures before reaching set trip points.
- Built-in Diagnostics: Monitors sensor health and communication integrity.
- API 670 Compliance: Meets strict safety standards for critical machinery protection.
- Oil & Gas: Protecting offshore platform compressors from overspeed.
- Power Generation: Safeguarding steam turbines in thermal power plants.
- Manufacturing: Controlling conveyor systems in automotive factories.
Case Study: A European refinery reduced unplanned downtime by 25% by deploying the 3500/53 133388-01 to detect rotor overspeed in centrifugal pumps, enabling predictive maintenance and saving $200,000 annually.
The 3500/53 133388-01 outperforms comparable modules by:
- Offering dual-channel redundancy (vs. single-channel alternatives).
- Supporting faster response times (50 ms vs. 100 ms).
- Including ROR detection as standard (not available in most legacy systems).
- System Complexity: Choose for multi-unit systems requiring fail-safe redundancy.
- Environment: Opt for this module in high-vibration or high-humidity settings.
- Integration: Pair with BENTLY’s 3500 Series framework for centralized monitoring.
- Sensor Calibration: Regularly verify probe alignment (0.5–1.5 mm gap for eddy current sensors).
- Cable Shielding: Use armored cables to prevent EMI interference.
- Firmware Updates: Install the latest updates via BENTLY’s 3500 组态软件 to enhance security.
