Active EMAT Transducer EMAT-A1

Active EMAT (Electromagnetic Acoustic Transducer) EMAT-A1, expand the capabilities of standard  flaw detector up to EMAT thickness gauge.



Measurement through the gap (rust): Up to 3mm



 Probe case: Durable aluminum alloy



 Device power supply: Rechargeable batteries



 Transducer on/off: Automatic





Сonvert flaw detector into an EMAT thickness gauge, compatible with the absolute majority of flaw detectors

Improvement of standard flaw detector

Active EMAT Transducer EMAT-A1 new technical improvement for classic flaw detector by electromagnetic acoustic unit and connected to a flaw detector instead of a conventional piezoelectric transducer.

EMA transducer compatible with various ultrasonic flaw detector that enable excitation with a bipolar pulse (any modern flaw detectors have this function).

The transducer can be used with any ultrasonic thickness gauge that enable bipolar excitation of the required amplitude.

The EMAT-A1 transducer enable to bring into force EMAT capabilities thru standard flaw detector function for a reasonable price.

EMAT A-1 combine with ud 3701

EMAT-A1 transducer will allow users:

– measure the thickness of metal products through rust;

– measure the thickness of metal products through coatings;

– measure the thickness of metal products through an air gap (contactless);

– take product profile through the surface’s scan (*through a special carriage, buying separately).

Active EMAT Transducer EMAT-A1 which has been purchased you get a combined flaw detector and EMAT thickness gauge for a quarter of its standard price.

Compact and autonomous

Active EMAT Transducer EMAT-A1 is powered by a replaceable battery type AA. Therefore, transducer compatible with classic AA batteries / accumulators and lithium-ion accumulators standardized size, 14500 (batteries / accumulators).

The transducer does not require turning on to start working and turning it off after the end of work. It turns on and off automatically in the presence of excitation pulses from the flaw detector.

Active EMAT Transducer EMAT-A1 (universal compatibility with various flaw detectors) expand the capabilities of any flaw detector!
