| Abstract | Reflective cavity pyrometers are increasingly used for on-line temperature sensing of metal sheets. The presence of the reflector increases the effective emissivity of the sheet, thus reducing the measurement error. Hemispherical geometries have been mostly used in the past for the reflector. This paper presents a Monte-Carlo analysis for a number of different cavity configurations. The value of the effective emissivity is evaluated for different cavity parameters and standoff range over the sheet as well as for different degrees of the metal sheet real emissivity. It will be shown, in particular, that a trucated hemisphere with centre of curvature belowthe sheet is preferable to the more conventional full hemisphere to reduce losses due to sheet fluttering. Applications to infurnace temperature monitoring of steel sheets will be indicated |
