Description

The Messko MR MT-ST160F/2/12M is a winding temperature gauge (WTG) manufactured by Maschinenfabrik Reinhausen in Germany, used to monitor the hottest-spot winding temperature in oil-filled power transformers. It uses a thermal image principle with a Pt100 sensor and a capillary tube of 12 meters length, providing 2 alarm/trip contacts at temperatures up to 160°C. The instrument provides both local indication and remote contacts for SCADA integration.
