About Zierhut Messtechnik
Zierhut Messtechnik GmbH was founded in Munich in 2000 and specializes in the measurement of electrical and optical signals using computer-assisted systems. The company develops sensors and complete systems for measurement tasks in thermal coating, in particular for plasma, wire, flame and arc spraying as well as HVOF/HVAF processes and LaserCladding. In addition, software for data analysis, data storage and data management is developed, along with consulting services in measurement and control engineering. The systems enable optical online process monitoring without intervention in the spray process as well as online measurement of layer properties such as layer thickness, roughness, layer spacing, component distortion and coating defects. Areas of application are manufacturing processes, quality assurance, process documentation and process automation, optimized for series production. The company is distinguished by patents and publications on plasma torches, arc wire spraying and diagnostic methods.
