Phototherm Dr. Petry GmbH

Phototherm is the solution provider for anyone operating painting and coating lines. The patented film thickness measurement technology developed by us based on thermal waves has provided for industrial-strength reliability for more than ten years now.

The measurement principle employed is simple: A laser beam causes the coating surface to heat slightly. The heat flows through the coating layer and is reflected by the substrate (metal). The thicker the coating the longer it takes the heat to be reflected by the substrate. The reflected heat is picked up by an infrared detector and converted by an electronic module, the reflection time being a measure of the coating thickness.

This patented technology for a substantial raw material savings potential, particularly in large-scale coating facilities. Other advantages: minimization of the reject rate, constant high quality, in addition to process automation capability. Documentation for quality management purposes is facilitated as well. The range of potential applications extends through virtually all industrial sectors: from automotive industries to steel furnishings, electrical-control cabinets, caravan sheet metals, heating radiators, kitchen appliances, metal ceilings (top panels) and building facades.
