ABSTRACT:
Sensors are provided for monitoring the speeds of a turbine and a compressor interconnected by a shaft. Signals from the sensors are used to control the direction of counting of a counter. If the shaft is intact, the counter repeatedly counts up from and returns to zero. If the shaft breaks, the counter counts upwardly and a signal is given when the count in the counter exceeds a threshold value.
