What is a High-Temperature Probe? 

A high-temperature probe is a bespoke instrument crafted to endure extreme thermal conditions, ensuring precise measurements are maintained. These probes are built with an emphasis on durability and accuracy, proving indispensable across a plethora of sectors. Notably, ultrasonic probes, designed for gauging thickness in high-heat environments, stand out for their application-specific utility. 

Their prowess in navigating demanding test scenarios guarantees the collection of trustworthy data, even under severe conditions. Utilised extensively in industrial domains, aerospace, and any sphere where temperature significantly impacts operations, a robust high-temperature probe is crucial. 

Its resilience against harsh environments, coupled with its capacity to deliver precise readings, renders it an essential asset for professionals aiming for reliable and consistent outcomes in their testing endeavours. 

How Does it Work? 

Our high-temperature probes, crafted for unparalleled precision, stand as indispensable instruments across a myriad of testing scenarios. These sophisticated devices harness the power of ultrasonic technology, a non-intrusive technique celebrated for its accuracy and adaptability. During operation, our probes dispatch high-frequency sound waves into the subject material. 

These waves permeate the material and are reflected back to the probe’s sensor. By gauging the duration for the waves’ return journey, our probes deduce the material’s thickness with remarkable accuracy. This method proves especially efficacious for appraising materials subjected to elevated temperatures, guaranteeing dependability under strenuous conditions. 

With Cygnus Instruments’ high-temperature probes at your disposal, you’re assured of precise outcomes for your testing requisites, even when operating in high-temperature environments.
