Abstract:
An apparatus for calibration of temperature sensors, comprising in combination a cavity (2; 22) for receiving a sensor (10; 30) to be calibrated, a heat-transferring medium (5; 25) for surrounding the sensor in said cavity, a means (40) for heating/cooling of said medium to a desired temperature, said cavity (2; 22) adapted to receive at least one sensor-surrounding thin-walled calibrator body (3; 23) which is made of a heat-conductive pliable material having a high thermal conductivity and which defines a volume (4; 24) which is filled with said heat-transferring medium, said calibrator body (3;23) having an inner wall (8; 28) defining at least a part of an inner opening (9; 29) for receiving at least one sensor (10; 30), and being under a pressure influence to bring said opening-defining wall (8; 28) of said calibrator body into tight-fitting abutment against said at least one sensor (10).
