ProTech-GII is a high-performance overspeed detection system device mainly used in turbine control or trip systems, which can safely shut down various sizes of steam, gas, and hydraulic turbines when overspeed or over acceleration events are detected. This device accurately monitors the speed and acceleration of the turbine rotor through active or passive MPUs (magneto electric speed sensors), and sends a shutdown command to the turbine's trip valve or corresponding trip system.

The characteristics of the ProTech-GII device include:

Quick response: The device can respond quickly and take corresponding protective measures to prevent serious damage to the turbine caused by overspeed or over acceleration events.

Highly integrated: This device has high integration and can interface with various control systems or factory DCS (distributed control system) to achieve fast data transmission and processing.

High reliability: The device uses high-quality electronic components and materials to ensure stable operation in harsh industrial environments. At the same time, the device also has multiple protection functions, which can prevent potential safety risks and equipment failures.

The protective effects of ProTech-GII devices mainly include:

Overspeed detection: This device can monitor the speed and acceleration of the turbine in real time. Once overspeed or over acceleration is detected, it immediately triggers a shutdown command to protect the turbine from overload or impact.

Fault diagnosis: This device has a fault diagnosis function, which can quickly locate the fault location and help maintenance personnel to repair and replace it in a timely manner.

Data recording and tracing: This device can record all relevant data, including speed, acceleration, fault codes, etc., to facilitate subsequent data analysis and tracing.

In summary, ProTech-GII, as a high-performance overspeed detection system device, has the characteristics of fast response, high integration, high reliability, and protection functions such as overspeed detection, fault diagnosis, and data recording and tracing. Widely used in various industrial fields for safety protection of steam, gas, and hydraulic turbines.
