Indicates the transformer’s oil temperature in Celsius degrees, sensitive to changes in temperature, the element is mounted on top of the transformer and is called thermowell, the thermowell is leak-proof, allowing the change of the thermometer without draining oil from the tank. In the thermowell a sensing bulb thermometer is housed, the bulb is connected to the instrument housing via flexible connection pipe consisting of a capillary tube.
- Remote assembly, that is, the thermowell at the top, and the indicator in the visible part for the operator. It comes with up to 3 to 6 meters capillaries length.
- Combination of switch contacts.
- Purely mechanical system, autonomous energy sources consumption measurement.
- Connection scheme ANSI, IEC.
