Operating instructions CellaCast PX 8x
The emissivity coefficient indicates the ratio of radiation of a real body (target) to
the radiation of an ideal black body (target) to the radiation of an ideal black body�
ε(λ): Emissivity coefficient of the object’s surface (targeted spot) at wavelengh λ
M: Emissivity coefficient of the object’s surface (targeted spot) at wavelength
MS: radiant energy emitted by a black body (perfect radiator)
Most burning, annealing and hardening furnaces emit a radiation of nearly ‚1‘
which corresponds to the conditions of a black body if the aperture through which
the measurement is made is relatively small�
5 Function
The pyrometer detects the radiated infrared radiation of objects without contact
and converts them into an electrical switching signal and an analogue output
signal�
