The sensor includes a thermopile (2) comprising several thermocouples (4) connected in series. The thermocouples each have a first region (6), which is exposed to radiation transmitted from an object being measured, and a second region, (8) which is in thermal contact with a heat conductor. A temperature sensor determines the temperature of the heat conductor. The thermocouples are arranged radially, such that the first regions lie at the centre of the arrangement, and the second regions lie at the edge of the radial arrangement. The radial arrangement of thermocouples is covered with a temperature-resistant film having a large absorption coefficient in the infrared range. |
