Abstract
A method of operating a temperature calibrator for calibrating a temperature sensor having a calibration block into which the temperature sensor is introduced and having a heating means by which the calibration block is heated and having a cooling unit by which the calibration block is cooled and an actuator by which the cooling unit is brought into thermal conductivity contact with the calibration block during cooling and is spatially separated from the calibration block during heating while forming an air gap. The invention further relates to a temperature calibrator is also disclosed.

A method of operating a temperature calibrator for calibrating a temperature sensor including:
- a calibration block into which the temperature sensor is introduced;
- a cooling contact surface located at the calibration block;
- a heating means by which the calibration block is heated;
- a cooling unit by which the calibration block is cooled;
- and
- an actuator,
- the method comprising bringing the cooling unit into thermal conductivity contact with the cooling contact surface of the calibration block during cooling and bringing the cooling unit to be spatially separated from the cooling contact surface of the calibration block on heating while forming an air gap by the actuator.
A temperature calibrator for calibrating a temperature sensor, comprising:
- a calibration block into which the temperature sensor is introduced;
- a cooling contact surface located at the calibration block;
- a heating means by which the calibration block is heatable;
- a cooling unit by which the calibration block is coolable;
- and
- an actuator is configured to generate or set an air gap between the cooling contact surface of the calibration block and the cooling unit.
