37DL PLUS
Corrosion Thickness Gage
Features
Patented Thru-Coat™ technology ■
measures and displays the thickness of
the metal part and its coating using a
‘single backwall echo’.
Temperature Compensation feature ■
adjusts the material velocity for changes
in material temperature.
Optional Oxide/Scale feature ■
measures and displays the thickness of
the steel and the oxide/scale build-up.
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.
Average/Min mode saves the average or ■
minimum of several successive thickness measurements.
A-scan display is brighter with better ■
contrast and visibility.
Uses a vast selection of dual element ■
and single element contact, delay line,
and immersion transducers.
EMAT transducers for no-couplant steel ■
thickness measurements through heavily
scaled surfaces.
The file-based alphanumeric datalogger ■

Transducers
The 37DL PLUS can be used with a vast selection of dual element and
single element transducers. Its full line of D790 series dual element
transducers feature Automatic Probe Recognition to provide maximum
gage performance for each transducer. The 37DL PLUS also has the ability
to use the E110-SB EMAT transducer for no-couplant steel thickness
measurements through oxide-scaled surfaces. The M2017 and M2091
transducers are ideally suited for measuring internal oxide/scale build-up
on boiler tubes. The 37DL PLUS is also compatible with the PanametricsNDT complete line of Microscan single element direct contact, delay line,
and immersion transducers ranging in frequency from 2 to 30 MHz. As
a result, the gage can be used for non-corrosion applications involving
materials such as plastic, fiberglass, composites, rubber, castings, rubber
and glass. Application Auto-Recall automatically recalls 16 default and 10
custom Microscan transducer setups from the gage’s memory.
