サの破壊検出機構。[Claims for Utility Model Registration] A first power supply terminal in which first, second, third, and fourth resistors are arranged in a bridge state, and connected between the first resistor and the second resistor. a second power supply terminal connected between the third resistor and the fourth resistor; a first output terminal connected between the first resistor and the third resistor; and a second output terminal connected between the resistor and the fourth resistor, the pressure of the gas and liquid is detected by a change in the resistance value of each of the resistors, and is sent to the first and second output terminals. In a pressure sensor that outputs, it is connected between the first power supply terminal and the first output terminal, and when the pressure sensor is broken, the potential of the first output terminal is shifted to the potential level of the first power supply terminal. a first detection resistor connected between the second power supply terminal and the second output terminal to change the potential of the second output terminal to the potential level of the second power supply terminal when the pressure sensor is broken; and a second detection resistor for causing the pressure to shift to , and is configured to detect destruction of the pressure sensor by detecting potential levels of the first and second output terminals. Destruction detection mechanism.
