Ultrasound measuring system for monitoring thinning of wall of pipe in nuclear power plant, has signal recorder compensating change in speed of sound of ultrasonic wave propagating through pipe using information on temperature of pipe
Ultrasound measuring system for monitoring thinning of wall of pipe in nuclear power plant, has signal recorder compensating change in speed of sound of ultrasonic wave propagating through pipe using information on temperature of pipe
The system has a high temperature mineral-insulated cable (102) having a blade connected to an ultrasonic transducer (101), where the cable includes a metal sleeve (112). An ultrasonic transmitter/receiver (117) causes the transducer to emit ultrasonic waves, and receive waves reflected by a pipe (106). A temperature measuring instrument (115) measures the temperature of the pipe. A signal recorder (104) compensates a change in speed of sound of an ultrasonic wave propagating through the pipe using information on the temperature of the pipe, and measures the thickness of the pipe.
