Description

The Messko MR MT-st-WWR/TT/6/12 is a winding temperature gauge made in Germany for power transformers, featuring remote resistance (WWR) and thermal image (TT) sensing via a 6 or 12-metre capillary tube. It provides up to 160°C measurement range and integrates microswitches for alarm and trip contacts. The WWR/TT configuration allows connection of external Pt100 sensors for precise winding hotspot emulation.
