Overview
The Bently Nevada 133388-01 3500/53 Overspeed Detection Module provides rapid and accurate overspeed protection for critical industrial machinery. Moreover, it meets API 670 and 612 standards, ensuring reliable operation in high-demand environments. The module integrates seamlessly into 3500 systems with redundant power supplies, enhancing operational safety and uptime.
This module is suitable for both 2-out-of-2 and 2-out-of-3 voting configurations, with the latter recommended for maximum reliability. Its compact form factor allows installation in standard 3500 racks while maintaining easy access for maintenance.
Functional Highlights
- Redundant Operation: Supports dual or triple voting systems for fail-safe overspeed detection.
- High-Speed Response: Detects overspeed conditions rapidly to protect critical machinery.
- Transducer Compatibility: Accepts signals from proximity probes or magnetic pickups, handling +10 V to –24 V input range.
- System Integration: Monitored speed is available through the Communications Gateway Module, while peak speed is displayed for reference.
In addition, this module operates reliably within harsh industrial conditions, tolerating –30 °C to +65 °C and up to 95% non-condensing humidity.
