ULTRASONIC PRECISION THICKNESS GAGES

The Panametrics-NDT™ Series 35
ultrasonic precision thickness gages
provide easy-to-use and cost-effective
solutions in applications where the
opposite side of the test material is
difficult or impossible to reach. These
rugged, pocket-sized gages make stable,
repeatable thickness measurements on
most materials of varied shapes and sizes.
Accurate thickness measurements are
displayed in large numerals on the backlit
LCD or can be viewed along with the live
waveform in the optional A-scan Mode.

NEW: LIVE A-SCAN (WAVEFORM)

AND ADJUST MODE

These full-featured gages include many
standard solution-oriented measurement
capabilities: Application Auto-Recall
to select and recall any of the stored
standard or custom transducer setups in
gage memory, Reduction Rate to track
the percentage of wall thinning, and
Velocity or Time of Flight Measurements
to directly measure material sound
velocity, as well as many other practical
measurement features.

35, 35DL, 35HP
& 35DL-HP

Precision Thickness Gages

Four models are available: 35 and 35DL
for measurements on metals, plastics, glass,
and other thin materials; and 35HP and
35DL-HP for sound attenuating materials
such as cast metals, thick rubber, fiberglass,
and composites. The 35DL and 35DL-HP
add a versatile file-based alphanumeric
data logger with incremental, sequential,
and 2-D grid file formats.

Operator can view thickness and waveform with the
optional A-scan mode

920-103

To thick materials ...

Measure depth to steel / ply cords in rubber conveyor
belts or tires.

Cylinder bores and many other cast metal parts or
sound-attenuating materials can be measured with
the 35HP gages.

35HP and 35DL-HP

Models 35HP and 35DL-HP are used
in sound-attenuating materials

With a very low ultrasonic frequency bandwidth and a special
pulser-receiver, the HP gages are specifically designed to optimize
ultrasound penetration when measuring thick, highly sound attenuat­ing or sound scattering materials. Typically these materials cannot be
measured with most other ultrasonic thickness gages.

The 35HP gages are excellent tools to measure fiber­glass or composite parts, from aerospace structures
to boat hulls and storage tanks that require thickness
control.

applications

- most thick or sound-attenuating
materials

- thick cast metal parts

- thick rubber tires, belts

- fiberglass boat hulls, storage tanks

- composite panels

- resolution of 0.01 mm or 0.001”

Why HP gages?

For more than three decades, Panametrics­NDT thickness gage engineers have developed
the HP (High Penetration) series specifically
for very sound-attenuating or thick materials.
Not only can these gages use transducers as
low as 0.5 MHz but their electronics (pulser­receiver) are highly optimized to process
signals at these low frequencies. The result
is that the Panametrics-NDT gages have
earned a reputation for superior performance
in measuring thick rubber, fiberglass,
composites, and other tough materials.

From thin materials...

The Model 35 with a delay line transducer or immer­sion bubbler makes accurate thickness measurements
on both convex and concave surfaces of turbine
blades.

Micrometers won’t work in this classic application.
Instead, the Model 35 with a M208 transducer makes
a thickness measurement up to a calibrated accuracy
of 0.001 mm (or 0.0001 inch) without breaking the
glass.

35 and 35DL

Models 35 and 35DL are used in the
majority of applications

The 35 and 35DL can use transducers ranging from 2.25 to 30 MHz,
which means that these versatile gages can solve the majority of
thickness gaging applications, from very thin to very thick. In general,
transducers with higher frequencies and smaller diameters allow
measurements of thinner or curved parts and enhance the accuracy
of the measurement.

Plastic or metal tubes and pipes of various diameters
can easily be measured ultrasonically with contact
type transducers. Small diameters may require immer­sion type measurements.

applications

- most materials, from thin to thick

- plastic bottles, tubes, pipes, sheets as
thin as 0.08 mm (or 0.003 inch)

- metal containers, steel coils, machined
parts as thin as 0.10 mm (or 0.004 inch)

- cylinder bores, turbine blades

- glass bulbs, bottles

- thin fiberglass, rubber, ceramics, and
composite materials

- curved areas or containers with
small radii

- resolution up to 0.001 mm or 0.0001”

From simple thickness measurements...

More than 40 years of experience has
made Panametrics-NDT ultrasonic
thickness gages the most advanced
and best known in the world. The new
pocket-sized 35 gages are no exception.
These practical gages offer more
measurement features and application­solving capabilities than their renowned
predecessors. All the more reasons for
you to consider the 35 gages for your
precision thickness gage application.

35 SERIES FEATURES

and custom setups

• Hand-held; weighs only 8.5 oz.
(0.24 kg)

• Min/Max Mode

Velocity measurement mode with direct Velocity
readout

MATERIAL SOUND VELOCITY
MEASUREMENTS

All 35 models have the capability
to make material sound velocity
measurements. This standard feature
is useful in applications where the
speed of the sound within the material
can be correlated to other properties.
Typical applications include cast metals
to monitor the degree of nodularity,
and composites/fiberglass to monitor
variations in density. Olympus NDT offers
a digital caliper for automatic transfer of
measurement thickness.

APPLICATION AUTO-RECALL
SIMPLIFIES GAGING

Application Auto-Recall simplifies making
thickness measurements. Select any of
the stored transducers and the 35 gages
recall all relevant internal transducer
parameters.

Stored Standard Setups

Standard setups include most commonly
used transducers.

Stored Custom Setups

Just in case your special application
problem cannot be solved with a
Standard Setup, these gages can create,
store, and recall as many as 20 Custom
Setups (10 with the 35 and 35HP).

You can measure critical thickness metal thinning
caused by bending.

REDUCTION RATE
MEASUREMENTS

Differential Mode and Reduction Rate
Mode are standard features on all models.
Differential Mode shows the thickness
variation from a pre-set thickness value.
Reduction Rate calculates and displays
the percent of thickness reduction after
a material thinning process. A typical
application is automotive sheet steel that
is bent and formed to make car body
panels.

Material thinning is displayed as a percentage.

to difficult applications...

Thickness and waveform of a very thin (0.004 inch
or 0.10 mm) sheet of steel.

NOW YOU CAN SEE THE
LIVE WAVEFORM AND MAKE
ADJUSTMENTS

An optional Live Waveform Mode on
all models permits the user to view the
ultrasound waveform (or A-scan) directly
on the gage’s display to make sure the
thickness reading is correct. The Adjust
Mode feature facilitates transducer setup
adjustments to maximize measurement
performance for challenging applications.

• High pixel density LCD renders sharp
trace of live waveform

• Permits real-time verification of
thickness readings

• Helps solve many difficult applications

• A Range, Delay, or Zoom allow
enlarging and centering to any section
of the waveform

• Permits adjustments of transducer
setup parameters

• Stores waveforms in data logger and
transfers to PC

35PCSCOPE

Optional 35PCSCOPE interface
software permits the instant display of
live ultrasonic waveforms and thickness
readings directly on your computer
screen. This is helpful when setup
parameters require closer examination.

Why ultrasonics?

Ultrasonic measurements are accurate, reliable, and
repeatable. Instant digital readings can be achieved by
transmitting sound into just one side of a material, making
it unnecessary to cut or destroy parts where the opposite
side is difficult to reach and where micrometers or other
inspection tools cannot do the job.

An optional protective rubber
boot protects the gage.

and data collection and management...

DATA COLLECTION FOR FAST AND
RELIABLE DOCUMENTATION

Internal Data Logger

The powerful 35DL and 35DL-HP internal
data loggers allows you to store, recall,
and transmit 8000 thickness readings

these gages can also store 350 wave
forms with thickness readings. All stored
information can be transmitted from
these units to your computer for statistical
analysis.
