High Temperature EMAT – 550°C
The HWS2220-VC High Temperature EMAT is designed for non-contact shear wave inspections on components up to 550°C without cooling. Utilising a magnetostrictive mechanism, this EMAT generates radially polarised bulk shear waves with robust signal strength on magnetic and magnetostrictive materials, making it ideal for applications in extreme environments such as energy generation, petrochemical, and oil and gas. Compatible with Sonemat’s GS2020, PR5000, and PR5020 systems, it is optimised for thickness gauging, flaw detection, and material analysis.
High Temperature EMAT – 200°C
The HWS2225-HT High Temperature EMAT is a robust shear wave transducer designed for pulse-echo inspections on conductive and magnetic components up to 200°C. Featuring a radially polarised design with a 3-5 MHz broadband frequency range, this EMAT operates without active cooling and provides consistent, non-contact performance, making it ideal for thickness gauging, flaw detection, and material analysis in industrial settings. Compatible with Sonemat’s GS2020, PR5000, and PR5020 systems, it is an essential tool for high-temperature NDT applications.
Water-cooled EMAT – 1000°C
The HWS2235-WCT is a high-temperature, water-cooled shear wave EMAT engineered for non-destructive testing on components reaching up to 1000°C. Featuring water-cooling to maintain optimal signal, this radially polarised EMAT is ideal for applications requiring pulse-echo testing on hot metallic and magnetic surfaces. Compatible with Sonemat’s GS2020, PR5000, and PR5020 systems, the HWS2235-WCT is a reliable solution for precise, high-temperature inspections across energy, petrochemical, and industrial sectors.
