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.

Abstract: A temperature calibrator for calibrating temperature function devices has an outer and an inner housing as well as a calibrator block. The calibrator block is radially spaced from the inner housing to form a flow space. The flow space is in communication with the environment at the upper end and at the lower end to generate a flow. A fan having a fan wheel that can be driven by a motor is connected to the flow space. The fan wheel is formed from a heat-resistant material; and the fan forms a predominantly closed surface in a plan view.

Abstract: A block calibrator for calibrating a temperature sensor with a heating block, on which or in which at least one heating appliance is disposed, and wherein the heating block features a receiving bore for receiving a calibration insert, into which a test object formed by a temperature sensor can be inserted. According to the invention, an air gap (L) is formed at least in certain areas between an internal wall of the receiving bore and an external wall of the calibration insert.
