description To provide an ultrasonic sensor system that can measure the thickness of a specimen at each position of a plurality of ultrasonic sensors while shortening the work time.SOLUTION: An ultrasonic sensor system comprises a plurality of ultrasonic sensors 1A to 1G fixed to a surface of a pipe 20 and located apart from each other, one sensor coil 2 fixed to the surface of the pipe 20 and connected to the plurality of ultrasonic sensors 1A to 1G, a sensor probe 5 having a transmission coil 3 and a reception coil 4 that can transmit and receive a signal to/from the sensor coil 2 through electromagnetic induction, and a controller 6. The plurality of ultrasonic sensors 1A to 1G have different resonance frequencies. The controller 6 performs variable control of the frequency of a pulse signal to allow for switching to the resonance frequencies of the plurality of ultrasonic sensors 1A to 1G, and identifies which one of the plurality of ultrasonic sensors 1A to 1G a waveform signal corresponding to the pulse signal belongs to.SELECTED DRAWING: Figure 1 【課題】作業時間の短縮を図りつつ、複数の超音波センサのそれぞれの位置における被検体の厚みを計測することができる超音波センサシステムを提供する。【解決手段】超音波センサシステムは、配管20の表面に固定されて互いに離間された複数の超音波センサ1A〜1Gと、配管20の表面に固定され、複数の超音波センサ1A〜1Gに接続された1つのセンサコイル2と、電磁誘導によってセンサコイル2との間で信号の送信及び受信が可能な送信コイル3及び受信コイル4を有するセンサプローブ5と、制御装置6とを備える。複数の超音波センサ1A〜1Gは、共振周波数が異なる。制御装置6は、複数の超音波センサ1A〜1Gの共振周波数に切り換わるようにパルス信号の周波数を可変制御し、パルス信号に対応する波形信号が複数の超音波センサ1A〜1Gのうちのいずれのものであるかを識別する。【選択図】図1
