摘要
In the present invention, there is disclosed a proportional strain sensor, particularly bone strain sensor comprising a thin-walled metal tube (3) wherein a strain-gauge bridge provided with strain gauges (1) is attached to said tube (3) inner walls. Inside said tube (3), in close proximity to the strain gauges (1), there is located a thermometer (2) with resistance, voltage or current output signal proportional to the measured temperature, particularly a resistance thermometer (2). The tube (3) is closed at its both ends wherein conductors of the thermometer (2) connecting thereof with an evaluation device (5) to measure its resistance and conductors of the strain-gauge bridge connecting thereof with an evaluation strain-gauge bridge (4) are passed through one end of said thin-walled tube (3).
