Thermometer with electrical contacts and micro contacts for the control, intervention and transmission of the alarm signal.
It is widely used on low/medium voltage oil-filled power transformers. It is designed and manufactured according to the specific needs of the customer, customizing the variables, such as: case diameter, range, number and type of electrical contacts, length and type of cable, maximum pointer adjustable from inside or outside, length and diameter of bulb and capillary, process connection.
This type of thermometer is designed to withstand vibrations that can be generated by the transformer during its use.
