Accurate temperature measurement at high voltages up to 6 kV
When temperatures need to be measured using Pt100 resistance thermometers in high-voltage environments, standard temperature transducers are often unsuitable due to their insufficient insulation.
Resistance thermometers can be isolated from high voltage. In practice, however, the available installation space is often too small. In addition, the insulation is weakened by thermal and mechanical aging.
Therefore, for measuring the temperature of power electronics components, maximum safety is ensured by high-voltage galvanic isolation. A typical application is to control the winding temperature of electric motors, generators or transformers.
Solution: Pt100 transmitter with 6 kV AC/DC basic isolation
The new ProLine P 44000 converter for high voltage applications converts the resistance of a 2- or 4-wire Pt100 resistance thermometer into a 4-20 mA signal with high accuracy and short delay time.
The output signal is galvanically isolated from the input signal and the supply voltage.
