Device for determining folding behavior and kinetics of surface of industrial coating in e.g. industrial system, has sensor arranged in chamber, where measuring light impinges on sensor to measure intensity alteration of light

摘要

The device has a gas probe (14) for measuring residue oxygen in inert gas atmosphere of a real-time kinetic chamber (1). A radiometric UV sensor (15) determines and adjusts radiation dose rate and -dose. A secondary light source (10) emits UV-free measuring light i.e. green light, and a sensor is arranged in the chamber. A light beam is projected on a color or paint sample such that reflected light impinges on the sensor with a photodiode (11) to measure intensity alteration of the measuring light in a reflectance mode relative to microfolding. The photodiode is a gallium nitrite-diode.
