Magnetic gauges only go to 400F and are affected by high temp. Can anyone suggest a product?

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.
