Abstract
The invention relates to a device (100) for calibrating the temperature of a fiber-optic temperature sensor, with which an optical fiber (10) of a fiber-optic temperature sensor is to be provided. The device (100) comprises a device body (101) having a passage (109) through which the optical fiber (10) is to pass, and a means for transferring heat energy. The device (100) further comprises at least one portion (160a), referred to as a first fixed point, which is made from a first material having at least a first predefined temperature at which the state thereof changes. The first fixed point (160a) is thermally connected to the optical fiber (10) when the optical fiber (10) is provided with the device (100). The heat-transferring means is arranged in the device body (101) such that, during the actuation thereof, the heat-transferring means exchanges heat energy with the first fixed point (160a) so as to cause a change in the state thereof at the first predefined temperature.
