Abstract

A measuring instrument to capture a physical/chemical measured value, including a sensor unit, which is linked via a contactless interface to a transmitter unit, for passing on to a central analysis unit, wherein the sensor unit includes an at least partly internal sensor element which vibrates against a sensor housing because of operation, and which is linked, contactlessly and inside the sensor unit, for sensor signal transmission, via a first transmission/reception unit, to a complementary second transmission/reception unit, which is arranged at a fixed location relative to the sensor housing, and which is also linked, contactlessly and outside the sensor unit, to a third transmission/reception unit of the transmitter unit.
