摘要： A buried type measuring instrument has a sensing unit 10A which is formed in part of a case 10 and senses a physical value pertaining to a change of state of a structure. This case 10 accommodates a transducer 11 for converting the physical value sensed by the sensing unit 10A; a transmission circuit unit 12 for outputting a carrier signal modulated by an output of the transducer 11; a drive unit 13 for driving the transducer 11 and the transmission circuit unit 12 with power supply from a battery 15; and a transmission coil 14 for receiving an output of the transmission circuit unit 12 and generating a low frequency magnetic field signal. This case 10 is buried in the structure. Consequently, it is possible to provide a measuring instrument which can adopt a radio communication mode to secure a sufficient cutoff function of the structure and avoid damage to the measuring sensor, allows remote data acquisition, and even has no adverse effect on strength characteristics of the structure.
