EMA-3T is a electromagnetic acoustic transducer (EMAT) ultrasonic thickness gauge that is different from any other. It is designed with the core principles of Industry 4.0 in mind to bring efficiency to the inspection process.
EMA-3T integrates asset identification (Barcode & RFID readers), inspection workflows and connectivity (Wi-Fi & Bluetooth) all within a practical ergonomic design.
Measuring through a gap and does not need to be perfectly aligned
Digital workflows from asset identification to end of inspection
Data recording and transmission allows inspectors to focus more on the inspection and less on paperwork

EMAT Technology
EMA-3T uses electromagnetic acoustic transducer (EMAT) technology to perform thickness measurements. This method allows significant advantages over standard piezoelectric thickness gauges for ultrasonic thickness inspections.
No paint removal required (non-contact up to 4 mm)
No surface preparation
No couplant required
Measures through unbonded paint
Sensor not required to be perpendicular to test material
Use in corroded areas
High temperature applications
Asset Identification
Asset database can be directly imported to EMA-3T before inspection
Integrated asset identification technologies (RFID and Barcode readers) allow identification of each asset and loads pre-defined inspection workflow in 2-clicks
Inspection Workflows
Interface includes standard functions such as A-scan, B-scan and 3 standard inspection workflows: Line, Matrix and Pipe
Desktop application allows customization of workflows based on customer’s requirements
Large internal memory allows multiple datasets (asset database, inspection results and workflows) to be synchronized to EMA-3T
Connectivity
Data transfer options: USB cable, Bluetooth or Wi-Fi
Wi-Fi data transfer between EMA-3T and database can be exchanged simultaneously
Ergonomic Design
Slim handle to allow users to operate with just one hand comfortably
Inclined display to reduce strain on the wrist during long working hours
High resolution display to provide clear visibility in direct sunlight
