Abstract:
A temperature sensor having a capillary tube or stem, sealed at both ends, with a thin bore defined therein is applied to the measurement of temperatures having a range of about -100Â to +400Â Centigrade. A bulb comprising a liquid reservoir, is provided at one end of the capillary tube, in liquid communication with the bore, and is generally filled with an ionic thermometric liquid. In the operation of the temperature sensor, temperature is measured by the height of the liquid in the bore.
