Description

The Messko MR MT-ST160F/4/12M (140°C) is an oil or winding temperature gauge manufactured by MR in Germany with a 12-metre capillary tube, four contact outputs, and a maximum reading of 140°C. It uses the gas-filled Bourdon tube principle for local temperature indication and provides four independently adjustable microswitches for alarm, cooling fan start, and trip relay activation. The 140°C version suits transformers with lower thermal limits.
