PEZZOTTI, Gianni; COPPA, Paolo and LIBERATI, Fabrizio. Pyrometer at low radiation for measuring the forehead skin temperature. Rev.fac.ing.univ. Antioquia [online]. 2006, n.38, pp. 128-135. ISSN 0120-6230.
This paper presents the results of the design, construction, calibration and tests of a low radiation pyrometer for temperature measurement of the human body. The instrument is based on a low cost thermopile as detector and an optical system. It is specially designed to measure the forehead temperature of a person. It is useful in applications like: Measurement of temperature of people in the airports (to prevent contamination with contagious diseases infection) or applications in medicine as continuous monitoring of the temperature of patients in intensive care units at hospitals. The instrument has been calibrated using an on-purpose-built black body and its precision is of 0.19 oC.
Keywords : low radiation pyrometer; thermopile; optical system; skin temperature.
