| Models 35 and 35DLare 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.
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" |
| 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. 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"
of 0.01 mm or 0.001" | | 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. | Why HP gages
For more than three decades, Panametrics-NDT 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 (pulser-receiver) 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. |
| | With reduction rate 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. | | 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). | | 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 . | | | Thickness and waveform of a very thin (0.004 inch or 0.10 mm) sheet of steel. | 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. |
| | Operator can view thickness and waveform with the optional A-scan mode | 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 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. |
