The 8237-1246 ProTech-Gll series overspeed detection system is a device for monitoring overspeed and excessive acceleration of turbines (such as steam turbines, gas turbines, water turbines, etc.).
It accurately monitors turbine rotor speed and acceleration through an active or passive MPU (electromagnetic pickup) and issues closing commands to the turbine speed closing valve or the corresponding trip system.
The 8237-1246 ProTech-GIl series speed detection system is a speed detection system produced by Bently Nevada, Inc. to detect the speed of rotating machinery.
The system has the following features:
1. High precision: The system uses advanced sensor and signal processing technology to accurately detect the overspeed of rotating machinery.
2. Multi-function: The system can not only detect overspeed conditions, but also detect other rotating machinery failures, such as vibration, temperature, etc.
3. Easy to install: The system adopts a modular design, easy to install and maintain.
4. Reliability: The system uses advanced electronic technology and manufacturing process, high reliability and long life.
The 8237-1246 ProTech-GIl series overspeed detection system is a device for monitoring overspeed and excessive acceleration of turbines (such as steam turbines, gas turbines, water turbines, etc.). It is done by initiative or by
The dynamic MPU (electromagnetic pickup) accurately monitors the speed acceleration of the turbine rotor and issues closing commands to the turbine speed closing valve or the corresponding trip system.
ProTech-GIl features include:
1. Comply with the provisions of API670 and API612, through IEC61508 SIL-3 certification, with reliability.
2. The turbine can be safely shut down when overspeed or excessive acceleration events are sensed.
3. Includes overspeed and overacceleration functions, as well as time-stamped alarm and trip records.
4. Optional module trip and alarm lockout states can also be configured to be shared with all other modules.
5. Provide a variety of predefined test procedures, including automated periodic test procedures, to help users verify system operation.
6. The triple module design allows the user to easily replace one of the modules (A, B, C) when the turbine is online and in normal operation.
In general, the 8237-1246 ProTech-II series overspeed detection system is a high-precision and reliable turbine safety protection device.
