The INPUD-T system is designed for the contactless transmission of temperature signals in a variety of processes. Usually signals from temperature sensors are transferred over mechanical or mercury slip rings from a rotating shaft to a stationary device. The transfer of these weak measuring signals is susceptible to interference. The slip rings need to be maintained or should be replaced from time to time. The use ofmercury slip rings has to be avoided in the food and pharmaceuticalsindustry. The INPUD-T contactless system works on an inductive principle and is able to transfer simultaneously up to four temperature-signals without any disturbance and no maintenance is necessary. The incoming transducer-signals are already amplified on the rotating part andtransferred as a digital data stream over the air gap. The stationaryhead decodes the data stream into 4 independent analog channels. Theoutput is an analog signal like 0..10V or 4..20mA. Linearization is also made in the stationary electronics. There are no moving parts or mechanical contacts to service or that could wear out.
