Model 38DL PLUS Using the EMAT Transducer

Back to Index

EMAT Transducer
An EMAT (Electro Magnetic Acoustic Transducer) uses the Magnetostrictive principle to generate shear wave sound energy in ferrous metals that are externally coated with high temperature oxide scale. E110-SB The EMAT transducer does not require the use of ultrasonic couplant. If the scale is not fully bonded to the surface of the steel, the shear wave sound energy will not be transmitted into the metal.

Back to Index

EMAT Transducer
?EMAT transducers are designed to be a quick way of determining the approximate wall thickness without removing the external oxide scale.
?The E110-SB EMAT transducers generate shear sound waves in the steel material. ?The EMAT transducers create a non-focused signal and is designed to give a good estimate of the remaining wall thickness (+/-0.010 in or +/-0.25 mm) ?EMAT transducers are relatively insensitive to small internal pits. ?The minimum capability is approximately 0.080 in. (2.0mm)
Back to Index

Connecting the E110-SB EMAT Transducer
LCB-74-4

38DL PLUS
E110-SB

The 1/2XA/E110 filter adapter must be plugged in to the transducer connectors located at the top of the 38DL PLUS. The E110-SB can then be connected to the 1/2XA/E110 adapter box using a standard Lemo to BNC cable. (LCB-74-4)

The 38DL PLUS will automatically recall the default setup for the E110-SB (EMAT) transducer when the Adapter and E110-SB is plugged in. The gage is now ready to take thickness measurements of steel that is coated with external scale using the default setup.
Back to Index

EMAT Transducer Calibration
For best accuracy it is recommended that the 38DL PLUS be calibrated using samples with external scale and known wall thickness. Perform the same Cal Vel and Cal Zero procedure that is outlined for any single element transducer.

Measure Type

? ?

For most single element transducer the Meas Type will be set to standard. Standard is for Standard Mode 1, Mode 2 and Mode 3 measurements. First Peak is a special algorithm to measure the first peak of a group of several peaks on either the positive or negative side of the waveform. Common uses would be for gel coat on fiberglass measurements or bolt elongation. Oxide Layer is a special measurement type used for displaying the thickness of boiler tubes and internal oxide at the same time. This feature is only available when the optional oxide software is activated Barrier is a special measurement algorithm used to measure the thickness of the barrier layer thickness in multi-layer plastic material. Typical applications are plastic fuel tanks, bottle preforms .
