PURPOSE:To simplify the structure of a gage, by constituting a sensor part by an organic elastic member, wherein a magnetic member and a magnetic sensor are provided so as to face each other with a specified interval being provided. CONSTITUTION:A sensor part 1 is constituted by an organic elastic member, wherein a magnet 2 and a magnetic sensor 3 are provided so as to face each other with a specified interval being provided. As the organic elastic member, e.g. rubber or synthetic resin can be used. In order to impact elasticity, however, many spherical cavity parts 4 are provided in the inside. The magnet 2 and the magnetic sensor 3 are implanted at both wall surfaces of said elastic member. When the sensor part 1, which is constituted in this way, is compressed, it is deformed and the interval between the magnet 2 and the magnetic sensor 3 becomes close in response to the compressing force. The DC output of the magnetic sensor 3 is amplified by a DC amplifier. The voltage is converted into frequency by an AD converter. The frequency is counted by a CPU, and the result is digitally displayed by a display device. |
