Shear Horizontal Wave EMAT
£1100
Key Advantages and Features:
-
- High-Sensitivity SH Wave Generation: Capable of generating guided SH waves with a standard 10 mm wavelength, these transducers offer effective defect detection and are optimized for operation around 300 kHz on steel.
- Non-Contact and Couplant-Free: Requires no couplants or surface preparation, making them ideal for use on rough or inaccessible surfaces, such as corrosion-prone pipelines and structural supports.
- Durable, Industrial-Grade Design: Built to withstand demanding environments with a metal wear face and Neodymium Iron Boride magnet array, the SHG1031-S and SHD1031-S provide lasting reliability in the field.
- Broad Compatibility: Designed for seamless integration with Sonemat’s TBPR1000 Toneburst Pulser, HPP2000 High Power Pulser, and other compatible systems, these EMATs support pitch-catch and pulse-echo configurations.
Applications:
-
- Corrosion monitoring in pipelines and tanks
- Structural defect detection in hard-to-access or high-stress environments
- Rail track inspections and thickness measurements
- Robotic scanning systems for complex or repetitive inspections

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.
