STATE DETERMINING DEVICE

To provide a state determining device for determining whether or not the state of a pressure transmitter is normal.SOLUTION: Provided is a state determining device 1 for determining the state of a pressure transmitter 106 that measures the gas pressure inside of a closure 105 attached to a cable 7, comprising: a call unit 10 for sequentially transmitting a plurality of call signals in a prescribed range that includes a call frequency for calling the pressure transmitter 106; a receive unit 20 for receiving a response signal to the call signal from the pressure transmitter 106; and a state determination unit 30 for determining, on the basis of the frequency of the call signal for which a response signal is obtained, whether or not the pressure transmitter 106 is normal. The state determination unit 30 determines as being normal when the frequency of the call signal for which a response signal is obtained falls within the standard range of call signal frequencies; otherwise, determines as being abnormal.SELECTED DRAWING: Figure 1 【課題】圧力発信器の状態が正常か否かを判定する状態判定装置を提供する。【解決手段】ケーブル７に取り付けられるクロージャ１０５内のガス圧力を測定する圧力発信器１０６の状態を判定する状態判定装置１であって、圧力発信器１０６を呼び出す呼出周波数を含む所定の範囲の複数の呼出信号を順次発信する呼出部１０と、圧力発信器１０６から呼出信号に対する応答信号を受信する受信部２０と、応答信号が得られた呼出信号の周波数に基づいて圧力発信器１０６が正常か否かを判定する状態判定部３０とを備え、状態判定部３０は、応答信号が得られた呼出信号の周波数が、呼出信号の周波数の規格の範囲に入っていれば正常と判定し、入っていなければ異常と判定する。【選択図】図１
