one such product. The component is essential to the function of the MESSKO® BeTech thermometer — and therefore also to the safe operation of power transformers. To reliably display oil and winding temperatures, the thermometers also need to withstand the most adverse weather conditions.

What’s more, before they are put into operation, each and every one has to pass extensive overpressure tests.
