Application Notes 65
In selecting a transducer for a corrosion application it is also necessary to consider the
temperature of the material to be measured. Not all duals are designed for high
temperature measurements. The chart above lists recommended temperature ranges
for the duals used with the 27MG Ultrasonic Thickness Gage. For other transducers,
consult the manufacturer. Using a transducer on materials whose temperature is
beyond the specified range can damage or destroy the transducer.
