ProLine P 44000

When temperatures are to be measured using Pt100 resistance thermometers in high-voltage environments, standard temperature transmitters are often unsuitable due to their insufficient insulation. Resistance thermometers can be insulated against high voltage. In practice, however, the available installation space is often too small. Moreover, the insulation is weakened by thermal and mechanical aging. For temperature measurement on power electronics components, maximum safety is therefore provided by high-voltage resistant galvanic isolation from the Pt100 resistance thermometer. A typical application is the monitoring of the winding temperature of electric motors, generators or transformers.
