Zusammenfassung:A capacitance-type deformation sensor e.g. for measuring the load on a vehicle axle comprises a first tubular body 2 in which there is fixed a first metal plate 5 and in which there is slidably mounted a second tubular body 7 to which a second metal plate 8, facing the first plate, is fixed. The abovementioned tubular bodies are provided with anchoring attachments 15 for connection to two points of a structure 17 the relative displacement of which is to be determined. Electronic circuitry 11 including e.g. a variable frequency oscillator and a frequency-voltage converter is mounted on a board 10 within the inner body 7.
