Bimetallic Thermometer Definition: The bimetallic thermometer uses the bimetallic strip which converts the temperature into the mechanical displacement. One type of thermometer is a narrow, concealed glass tube containing mercury or alcohol which extends along the tube as it expands. D Same temperature on a Celsius thermometer. Purpose. Another type is a digital thermometer, which uses electronics to … Thermometer Definition. Another word for thermometer. A thermometer is a device that is used to measure the temperature of a body. A thermometer is a device used to measure temperature. A thermometer has two important elements: (1) a temperature sensor (e.g. Note: some partial immersion thermometers do not have an immersion line inscribed; ie, thermometers with standard taper joints, or thermometers with very short immersions, such as for melting point applications. The thermal expansion is the tendency of metal in which the volume of metal changes with the variation in temperature. Find more ways to say thermometer, along with related words, antonyms and example phrases at Thesaurus.com, the world's most trusted free thesaurus. For very high or very low temperatures, as well as for very accurate measurements, liquid-in-glass thermometers are not suitable. Various types of electrical thermometers are used instead. NOTE: In order to assist you with reading the patient’s temperature, most thermometers have an arrow pointing to the line denoting the average normal body temperature (98.6º F or 37º C).
