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

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”
