Magnetic gauges only go to 400F and are affected by high temp. Can anyone suggest a product?    Reply  Translate  Close   Joseph P Joseph P 03:58 Apr-27-2000 Re: Measuring Coating Thickness at Hig Temps : Im currently looking for an instrument to read thickness of a non-ferrous coating on a ferrous substrate, with a surface temp of 500 F.

Magnetic gauges only go to 400F and are affected by high temp. Can anyone suggest a product? What is the coating material and what is the thickness range? It may be possible to do this ultrasonically, using a high temperature delay line transducer, but I need more information about exactly what you're measuring to comment further. --Tom Nelligan Panametrics, Inc.    Reply  Translate  Close
