Thermistor-Working Principle, Types and Applications
WebPrinciple of thermometer states that liquid expands on heating and contracts on cooling. These liquid thermometers are based on the principal of thermal expansion. When a … A thermometer is a device that measures temperature or a temperature gradient (the degree of hotness or coldness of an object). A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which … See more While an individual thermometer is able to measure degrees of hotness, the readings on two thermometers cannot be compared unless they conform to an agreed scale. Today there is an absolute thermodynamic temperature scale. … See more Thermometers may be described as empirical or absolute. Absolute thermometers are calibrated numerically by the … See more Thermometers can be calibrated either by comparing them with other calibrated thermometers or by checking them against known fixed points on the temperature scale. … See more Thermal expansion Utilizing the property of thermal expansion of various phases of matter. Pairs of solid metals with different expansion coefficients can be used for bi-metal mechanical thermometers. Another design using this principle is Breguet's thermometer. Some … See more Traditional thermometers were all non-registering thermometers. That is, the thermometer did not hold the temperature reading after it was moved to a place with a different … See more A thermometer is called primary or secondary based on how the raw physical quantity it measures is mapped to a temperature. As summarized by Kauppinen et al., … See more The precision or resolution of a thermometer is simply to what fraction of a degree it is possible to make a reading. For high … See more hbm telai
