FIELD: construction.
SUBSTANCE: strain gauge is made in the form of a sealed cylindrical body with a sliding stem. Inside the body there is a capacitance primary converter, one electrode of which is fixed on the body, and the second one - on the sliding stem. Inside the body there is a secondary metering converter, which carries out conversion of electrical capacitance into a digital code. The sliding stem of the converter is equipped with a sliding radial seal and a tail with micrometrical thread and two stop nuts, on one of which there is a vernier scale.
EFFECT: elimination of noise effect, possibility to transfer data along a cable communication line to a large distance without distortions, increased operational reliability, possibility to tune and to realise metrological monitoring of a strain gauge in place of operation.
