Determination of thermal emissivities within seconds
The TIR 100-2 measures thermal emissivities of surfaces within some few seconds. The measurement can be performed directly at the original part and even structured and curved surfaces can be measured. The instrument contains all operating elements and electronic components for the measuring and processing of the sensor signals and their display, as well as for the control of the black-body temperature. The TIR100-2 is the follow up device of the known TIR100 for measuring thermal emissivities of surfaces. We combined the reliable technology of the TIR100 with highly integrated electronics and a comfortable touch screen. The stand - alone instrument is now more compact and easier to use.Inside a microcontroller regulates the temperature of the radiator to a constant value of T =100°C. At the same time the signal of the sensor is registrated and converted by the help of the stored standard values into an absolute value of emissivity. The large LED illuminated display shows instrument status, measuring results and operational menues. The touch screen panel guarantees easy operation of all functions. The essential part of the instrument is the half sphere shaped black body. Due to its black coating the radiator has all the properties of a nearly ideal 'black body'. The radiator works at100°C. The remaining part of the black body housing has been thermally insulated against the radiator. There is a slight heating of the device during operation. The heating of the radiator is protected against overheating with a reversible thermo-fuse, which will interrupt the heating at a temperature of125°C. The thermopile sensor changes the reflected thermal radiation into a voltage signal. The spectral distribution of the thermal radiation is given by Planck's law of a black body at given temperature. More than 97 % of the radiation energy is ranging in the wave length region between 2.5 μm and 40 μm.
