Physical basics

Above absolute zero (-237.18 °C) all bodies emit energy radiation in form of electromagnetic
waves. This radiation is often designated as thermal radiation or infrared radiation. The wave-
length of the maximum radiation is moving towards visible area with rising temperature.
This can be found on glowing materials starting from deep red to yellow and finally to white glow.
►distance in-between the object to be measured and lens leading edge
of the pyrometer
►object temperature is going to be measured.
►System to define temperature of a source by comparison with a
standard light source (usually with help of human eyes).
►pyrometer which is nearly sensitive to heat radiation in the whole
spectral range.
►instrument to measure temperatures without making contact with the
object to be measured (radiation thermometer)
►pyrometer using signals from two close to each other spectral ranges
and ratio formation to find out the temperature
►uncertainty to repeat a measurement value at same condition
►standardised serial interface for digital communication
►interface that allows higher number of receivers and senders at one
wire
►equipment to re-direct the pyrometer radiation setting to a line vertical
to the optic axis, so that the surface of the object can be scanned.
The scanner moves the spot sizes across the object.
►area of spectral range which is used by the pyrometer when taking
readings
►area on the object from which the pyrometer receives most (90%)
of the signals
►ambient temperature to store and use the pyrometer correctly.
►optical accessory for accurate pyrometer adjustment
►the passing of radiation through a solid, liquid or gas; the transmission
coefficient gives the ratio between intensity of radiation that has passed
through, to the incoming radiation.
►describes the length of a wave between two points in a single phase
