Abstract
An optical temperature sensor head having an optical fibre and a sensor material, which is optically connected to a free end of the optical fibre. The free end of the optical fibre has an overmould made of a plastics material, which engages over a free end of the optical fibre and forms a protective body. A transparent window is arranged in the protective body. The window permits an optical connection with the free end of the optical fibre. Luminescence radiation from a sensor material can enter the optical fibre. The protective body has the effect that the temperature sensor head is mechanically stable and is insensitive to environmental influences. A temperature sensor device having such a temperature sensor head. An electric machine having a winding with a winding wire, which is connected to a proposed temperature sensor head.
