Description
BENTLY 133396-01 Overspeed Detection I/O Module
1. Product Description
The BENTLY 133396-01 is a high-precision overspeed detection module designed for the BENTLY 3500 Machinery Protection System, ensuring reliable and rapid protection for rotating equipment in critical industrial environments. It monitors shaft speed in real time, triggers alarms, and initiates shutdowns to prevent overspeed-related failures. Rated for API 670 and API 612 compliance, the BENTLY 133396-01 supports redundant configurations (2-out-of-2 or 2-out-of-3 voting systems) and integrates seamlessly with BENTLY’s 3500 Rack system. Its compact design and wide compatibility with proximity probes and magnetic pickups make it ideal for power plants, refineries, and manufacturing facilities.

4. Application Areas and Case Studies
Industries:
- Petrochemicals
- Power generation
- Aerospace
- Heavy machinery manufacturing
Case Study:
A Middle Eastern refinery implemented the BENTLY 133396-01 to protect centrifugal compressors. The module detected a 12% speed surge during startup, triggering an immediate shutdown and avoiding a $1.5 million loss in production downtime.

5. Competitive Comparison
The BENTLY 133396-01 outperforms generic overspeed modules with its API-rated redundancy and direct integration with BENTLY’s 3500 Rack system. Unlike standalone solutions, it leverages BENTLY’s proven vibration and speed monitoring algorithms, reducing calibration efforts and improving accuracy. Its wide temperature range and epoxy-sealed design also offer better durability than competing models.
6. Selection Recommendations
- System Redundancy: Opt for a 2-out-of-3 configuration for critical machinery.
- Sensor Type: Ensure compatibility with your existing proximity probes or magnetic pickups.
- Power Requirements: Verify 3500 Rack power supply capacity for multiple modules.
7. Installation and Usage Notes
- Static Protection: Handle the module with anti-static gear to avoid component damage.
- Calibration: Use BENTLY’s TK3 Probe Checker for sensor alignment.
- Bypass Mode: Avoid prolonged use to maintain safety integrity.
