DMTA-10004-01EN, Rev. D, November 2016
The 38DL PLUS simultaneously displays a thickness readout and an A-scan view for
waveform verification. The microprocessor of the 38DL PLUS continuously adjusts
the receiver setup so that every measurement is optimized for reliability, range,
sensitivity, and accuracy. An advanced internal datalogger can store up to
475000 thickness measurements and 20000 waveforms.
The 38DL PLUS operates with a full line of single element and dual element
transducers to measure material thicknesses between 0.08 mm and 635 mm (0.003 in.
and 25 in.). The temperature range of measured materials can be between −20 °C and
500 °C (−4 °F and 932 °F) depending on the material characteristics, the transducer,
and the measurement mode. You can also use single element or dual element
transducers for echo-to-echo measurements.
You can connect the 38DL PLUS to a printer and to a computer using the bidirectional
serial USB/RS-232 communication ports.
