Thickness measurement at elevated temperatures is a special category. Standard transducers are not designed to withstand elevated temperatures and will get damaged/destroyed due to varying thermal expansion coefficients of the materials used to construct them. Variation in material temperature affects sound velocity and accuracy of thickness measurements.
We use PowerBox H from M/s. Innerspec Technologies Inc., USA to offer high temperature thickness gauging. PowerBox H works on
EMAT Principle
were thickness gauging is done without couplant as a result the system is c
apable of performing thickness gauging in temperatures from
-30ºC to 650ºC
with no active cooling.
