GAD-A type guide vane link signal alarm device is used to monitor the states of guide vane bending link and shear pin to satisfy the needs for automation monitoring of modern power plant. Failure of the guide vane will cause the act of bending link or shear pin. So it is very important for monitoring, immediately sending out the alarm signal.

GAD-A type guide vane link signal alarm device consists of input interface, CPU, expander circuits, display and operating circuits. It has advanced practical functions of monitoring the states of guide vane bending link and shear pin automatically, auto searching the faults, digital display, and alarm output. This device works reliably with steady performance and advanced technology
