Description

The Qualitrol winding temperature gauge (50°C, 12 m, 4-switch) is a Swedish-made transformer monitoring instrument with a 12-metre capillary sensing tube rated for lower-temperature applications, configured with four alarm/trip contacts. It is used in transformer installations requiring remote temperature monitoring at lower hotspot temperatures, such as dry-type or special application transformers. The four-switch configuration allows independent alarm, cooling, and trip setpoints.
