A temperature measuring system and a sensor unit of such a temperature measuring system

摘要

The invention relates to a temperature measuring system for the contactless determination of the object temperature (Tv) of at least a part of an object. The system is provided with a sensor unit (2) which is to be placed near the object and which comprises a first and second metal plate (4, 14 respectively). A temperature-sensitive sensor is disposed on each plate to produce first and second sensor signals (10, 18 respectively) which represent the temperature of the first plate (4) and second plate (14) respectively. The system also includes a control unit (12) which processes the first and second sensor signals (10, 18) in combination for determining the object temperature (Tv). Use is preferably made of a Kalman filter.
