  • Method of measuring ambient temperature and a temperature measurement arrangement
    Patent number: 6817756
    Abstract: The invention relates to a method and an arrangement for measuring the ambient temperature in barely accessible or hazardous locations, in particular in the proximity of textile, paper or similar webs or other work pieces or materials being conveyed, of which at least one property is determined by means of a methodical system, which requires at least the direct ambient temperature as a comparative or reference value. According to the invention, a pyrometric radiation meter known per se is used. A thermal radiator in thermal balance with the environment is positioned directly proximate to the material web. Detection of the heat radiation spectrum and hence an indirect determination of the ambient temperature is carried out by means of the pyrometer via said thermal radiator.
