DEVICE FOR TEMPERATURE CALIBRATION METHODS TEMPERATURE CALIBRATION AND POSITIONING OF FIBRE-OPTIC TEMPERATURE SENSOR Russian patent published in 2016 - IPC G01K11/32 G01K15/00 

FIELD: measuring equipment.

SUBSTANCE: invention can be used for temperature measurement by means of optical fibre. Disclosed is device (100) for temperature calibration of fibre-optic temperature sensor intended for equipment of optical fibre (10) of fibre-optic temperature sensor. Device (100) includes housing (101) of device containing passage (109) for optical fibre (10), and heat energy transfer device. Device (100) also contains at least one section (160a), called first fixed point made of first material, having at least first preset temperature of condition change. First fixed point (160a) communicates with optical fibre (10) when optical fibre (10) is equipped with device (100). In device housing (101) heat transfer facility is arranged so that during its actuation heat transfer facility exchanged thermal energy with first fixed point (160a) to cause change of its state at first preset temperature.

EFFECT: higher accuracy of temperature measurements.
