Coating thickness measurement

BST ProControl offers in the coating thickness measurement field, next to the infrared sensors and the transmission sensors, the comparison of the optical layer thickness with the wavelengths of light. 

IndiSpectro®

The coating thickness measurement is based on the comparison of the optical coating thicknesses with the wave lengths of the light. Light irradiated on a transparent layer is partially reflected at the upper as well as at the lower interface

IR-Sensor - Patented infrared sensor technology CONESPLIT® Same Spot Technology

Usually, Infrared sensors are offered as back-scattering sensors. Though if necessary, the construction as a transmission sensor is possible as well. Based on a patented measuring method, CONESPLIT® Same Spot Technology for coating thickness measurement represents an advantage that sets BST ProControl apart from the competition.

SHADEX Sensor

The non-contact measurement principle bases on the precise definition of a linear fanned out laser beam. The thickness of the material causes the shading within the measuring area and a proportional influence of the receiver diode takes place.  A distance measuring system compensates the distance changes between the sensor and the reference roller, whereupon the results are evaluated by a special digital signal processing technique which determines the exact material thickness.
