Abstract

　高周波焼入れ監視装置（２０）は、高周波インバータ（１１）の出力電流を検出する電流センサ（２１）と、高周波インバータ（１１）の出力端子間にコンデンサ（１２）と共に等価回路的に接続される加熱コイル（１５）における電圧を検出する電圧センサと、電流センサ（２１）の検出信号と電圧センサ（２２）の検出信号とに基づいて焼入れ管理を行う制御部（２３）と、を含み、制御部（２３）は、電流センサ（２１）からの検出信号に基づいて高周波インバータ（１１）からの出力電流の実効値を算出すると共に電圧センサ（２２）からの検出信号に基づいて加熱コイル（１４）に生じる電圧の実効値を算出するか、さらに各実効値から負荷インピーダンスを算出することで焼入れの監視を行う。
