Overview

The TRI-SEN Turbosafe 1000048-001 is a specialized electronic overspeed trip device designed for turbines and other high-value rotating machinery. It uses magnetic speed sensors and a triplicated measurement architecture to ensure highly reliable overspeed detection. Moreover, its two-out-of-three (2oo3) hardware voting logic meets stringent API 670 requirements, making it suitable for safety-critical applications in power generation, petrochemical facilities, and heavy industrial processes. In addition, the unit provides advanced diagnostics, event logging, and communication interfaces for integration with modern control systems.
