Description

The Qualitrol winding temperature gauge (160°C, 12 m, 4-switch) is a Swedish-made transformer winding hotspot monitor with a 12-metre capillary tube and four independent microswitch contacts. The extended capillary length allows flexible installation where the gauge head is located far from the transformer winding sensing point. It is used on large power transformers requiring long-distance thermal monitoring with multiple alarm and trip setpoints.
