Description

The Qualitrol Oil Temperature Gauge (130°C, 6 m, 4-switch) is a capillary-type thermometer manufactured in Sweden for monitoring top oil temperature in power transformers. The 6-metre capillary connects the temperature sensing bulb (submerged in transformer oil) to the dial indicator and four microswitch contacts, settable to different temperatures for alarm and trip purposes. The 130°C maximum range suits distribution and medium-power transformers.
