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?

Measuring Coating Thickness at High Temps
The Lixi Profiler can measure at high temperature the thickness of a coating on ferrous material if the X-Ray absorption of the coating is at least 2% of the ferrous material

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.

ISAFE3 Intrinsically Safe Sensor System

ISAFE3 intrinsically safe sensor system of Vallen Systeme is especially targeted at the petrochemica
...
l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
