Product Description
The Woodward 8237‑1247 is a ProTech‑GII overspeed protection device engineered to provide independent, high-speed shutdown protection for industrial turbines. It continuously monitors rotor speed and acceleration using active or passive magnetic pickup (MPU) sensors and triggers a rapid trip signal to the turbine’s trip valve or safety system when overspeed conditions occur.
Designed for harsh industrial environments, this bulkhead-mounted device features an IP56 dust- and water-resistant enclosure and operates reliably across wide temperature and humidity ranges. Moreover, it ensures deterministic, fail-safe protection as a dedicated safety layer, complementing primary turbine control systems.
The 8237‑1247 is suitable for steam and gas turbines, providing critical overspeed protection to prevent mechanical damage and enhance operational safety. Its ruggedized construction and precise monitoring capabilities make it essential for high-risk, mission-critical turbine applications.
