Notch probe for motors and transformers

Principle of construction / operation

In these groove resistance thermometers, instead of a bifilar wound platinum wire, a platinum thin-film measuring resistor. The temperature-sensitive length is shortened to the active measuring length of the thin-film sensor (spot measurement). This is quite sufficient for the many measuring purposes, since the requirements are mainly on the design (groove) and not on the active measuring length.
