Precision Thickness Gage Transducer Ranges for Metals, Plastics and Miscellaneous Materials
These tables are intended as a general guideline only, listing only the most commonly used Microscan transducers and typical material thickness ranges when used with the Olympus Model 38DL PLUS and 45MG gages (45MG-SE or 45MG-HP software option required.) All thickness ranges are approximate and should be used as a starting point. The actual measurement range in a given case will always depend on instrument setup as well as material properties such as part geometry, surface condition, and grain structure.
In many cases, these measurement ranges will require an optimized gage setup where gain and blanking have been adjusted by a trained operator. The pre-programmed transducer default setups can always be used as a starting point, but performance can be often optimized and range extended with some simple setup adjustments. Contact Olympus for details.
Your choices also depend on geometry, temperature and resolution. Please consider the follloiwng before making your selections.
| Name | Description |
| High Resolution | Measurement to 0.0001” or 0.001 mm resolution. Usually recommended only when measuring smooth, acoustically transmissive materials like most metals and ceramics with delay line transducers. |
| Small Radius |
Measurement on curved surfaces with radiuses smaller than approximately 50 mm or 2”. This requires small diameter transducers.
Below 1.000” OD: Use 0.250” diameter transducer or smaller Below 0.500” OD: Use 0.125” diameter transducer or smaller Below 0.250” OD: Use V260 Sonopen Below 0.125” OD: Use immersion transducers Consult Olympus for details. |
| High Temperature | Surface temperature greater than 50º C or 125º F. In such cases a high temperature delay line transducer must be used. |
