Product Overview
The Woodward 8237-1369 ProTech-GII overspeed protection device is a high-reliability safety system designed to safeguard steam, gas, and hydro turbines from catastrophic damage caused by overspeed or over-acceleration events. As part of Woodward’s ProTech-GII series, this device combines advanced monitoring capabilities with redundant architecture to ensure critical industrial systems operate within safe parameters.Whatsapp:+86 18859254943.
Engineered for mission-critical applications, the 8237-1369 continuously monitors turbine speed using 4-20 mA inputs from magnetic pickups (MPUs) and triggers emergency shutdowns when predefined thresholds are exceeded. Its triple modular design (A, B, C modules) supports 2-out-of-3 voting logic, ensuring fail-safe operation even if one module malfunctions. This redundancy is vital for industries where downtime translates to significant financial losses, such as power generation and oil & gas production.
In automation systems, the 8237-1369 acts as a standalone safety layer, interfacing with turbine control systems to provide real-time speed feedback and trip signals. Its Modbus communication capability enables seamless integration with higher-level SCADA or DCS systems, facilitating remote monitoring and diagnostics. With a response time of 12 milliseconds and a speed range of 0.5–32,000 RPM, this device delivers precision and agility in protecting rotating equipment.E-mail :sales@ygplc.com.
