Many applications call for transducers to be used in harsh environments, such as high temperatures. The Phoenix range of high temperature probes allow rapid and cost effective testing by removing the need to cool surfaces in advance and is available in a variety of transducer designs to perform reliably on surfaces at temperatures from 80°C to 200°C.
Special formulated high temperature couplants are required for use with these probes and care should be taken to use the correct couplant for the temperature of the component to be inspected. As a general guideline duty cycles of no more than 10 seconds with the hot surface followed by a minute of air cooling is advised.
