Olympus 37DL PLUS Manual

Advanced Ultrasonic Corrosion Gage
The Panametrics-NDT™ 37DL PLUS is
an advanced nondestructive ultrasonic
thickness gage that combines powerful
measurement features with sophisticated
data acquisition and output capabilities for
applications involving pipes, tanks, and
other metal structures subject to internal
corrosion or erosion. The 37DL PLUS
includes many innovative features that
simplify true metal thickness measurements
even when the exposed surface is coated
or painted. The patented Thru-Coat
technology measures and displays the
thickness of the metal part and its coating
using a 'single backwall echo'. A Oxide/
Scale option measures and displays the
thickness of the steel and the oxide/scale
build-up on the inside of boiler tubes to
help predict tube life. Accuracy of high
temperature thickness measurements can
be improved by using the Temperature
Compensation feature that adjusts the
material velocity for changes in material
temperature. A new Average/Min mode
saves the average or minimum of several
successive thickness measurements.
The A-scan display is bright with great
contrast and visibility. Every thickness
reading in a stored B-scan can be reviewed
on the 37DL PLUS and in the Interface
Program. The user can select to view (Min/
Max, Alarm, or A-scan flags) flags with
Grid points. The file-based alphanumeric
datalogger can use longer file names
(32 character max) and ID numbers (20
character max). Grid files can be expanded
by adding rows or columns or by changing
the incrementing direction.
