Abstract
A contact thermometer for determining-temperature of an inner wall of a cavity, where accuracy and speed response is assured by use of a probe having a variable geometry where the first shape of the probe exists before and during placing the probe into a cavity and the second shape is formed during the measurement process. The temperature measuring tip of the probe makes an intimate thermal contact with an inner wall of a cavity after the second geometrical shape is assumed. The accuracy is assured by use of at least two temperature sensors while the speed response is improved by taking at least two readings, from one temperature sensor.
