<p>A method for contactless detection of preferably mechanic measuring quantities such as torque, force or pressure, characterised in that a measuring quantity actuates a mechanic resonance in a string shaped element and that said resonance is excited by naturally appearing vibrations or movements in the vicinity of the sensor. The sensor is radiated with for instance microwave energy and a modulation of the microwave signal caused by the mechanic oscillation of the string element of the sensor. The distance between the sensor and the microwave transceiver can be > 10 m.</p> |
