Webb2 aug. 2016 · Let’s start our story with one of the most common thermometers used today, the liquid-in-glass (LiG) thermometer. A LiG thermometer, by definition, is a glass capillary tube with a liquid-filled bulb at one end. As the temperature of the liquid in the reservoir increases, it expands and rises into the capillary tube. WebbConstant pressure gas thermometer In this type of thermometer, pressure remains constant whereas volume changes on changing temperature. It is based on Charles’s …
WebbFor a constant pressure gas thermometer if we use the ideal gas equation then we will see that temperature depends only on the volume as other terms are constant. Thus for measuring temperature, the change in volume of the thermometric fluid is … WebbConstant volume gas thermometer measures temperature in the range 0k to 500 k. Platinum Resistance Thermometer Platinum Resistance Thermometers use a platinum …
Thermometers are used in roadways in cold weather climates to help determine if icing conditions exist. Indoors, thermistors are used in climate control systems such as air conditioners, freezers, heaters, refrigerators, and water heaters. Galileo thermometers are used to measure indoor air temperature, due to … Visa mer 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 Visa mer Thermometers may be described as empirical or absolute. Absolute thermometers are calibrated numerically by the thermodynamic absolute temperature scale. Empirical thermometers are not in general necessarily in exact … Visa mer Thermometers can be calibrated either by comparing them with other calibrated thermometers or by checking them against known fixed points on the temperature scale. The best known of these fixed points are the melting and boiling points of pure … Visa mer While an individual thermometer is able to measure degrees of hotness, the readings on two thermometers cannot be compared unless they conform … Visa mer Traditional thermometers were all non-registering thermometers. That is, the thermometer did not hold the temperature reading after it was … Visa mer 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., "For … Visa mer The precision or resolution of a thermometer is simply to what fraction of a degree it is possible to make a reading. For high temperature work it may only be possible to measure … Visa mer WebbThe thermal time constant is given by the following equation, τ th = ρV C hAS τ t h = ρ V C h A S Where, ρ = Density of the body V = Volume of the body C = Specific heat of an object …
