ABSTRACT:
Calibrating temperature sensors of weathering devices by means of contactless temperature measurementA temperature sensor (10) which is, for example, designed as a black standard sensor and is typically used in apparatuses for artificial weathering of material samples, has in a known way a stainless steel plate (1) which is provided with a black coating (2) and is thermally coupled at its rear side to a platinum resistor (3). The output signal of the electric measurement transducer circuit connected to the platinum resistor (3) by means of feeder wires (4) can be calibrated with the surface temperature measured in a contactless fashion by a pyrometer (8). The calibration operation can be carried out under the conditions prevailing in a weathering device, that is to say while applying to the surface of the sensor the optical radiation of a xenon radiation source (7) and an airstream (9) parallel to the surface.
