Abstract
The invention relates to a system for detecting the rotational motion of a shaft in a machine housing, comprising a measuring transmitter, which is connected to the shaft, at least one measuring sensor, which is provided on the machine housing, and a measuring transducer connected to a measuring sensor. The invention is characterized in that the measuring sensor(s) (8 and 15 to 20) is/are supplied with current by a separate energy accumulator (11).
Claims6
A system for detecting a rotational motion of a shaft in a machine housing comprising:
- a seal disposed on the shaft;
- a measuring transmitter connected to the shaft;
- at least one measuring sensor provided on the machine housing;
- a measuring transducer connected to the measuring sensor;
- a regulator that regulates the electric current;
- and
