Brown & Sharpe/TESA Wireless Inductive Probes

September 01, 2014

Hexagon Metrology announced its new line of Brown & Sharpe/TESA wireless inductive probes with technical features that are reportedly unique to the metrology marketplace. The new inductive probes introduce wireless bidirectional communication, and enable fast, reliable and synchronized measurements in both static and dynamic modes even when a measurement instrument is moving or under acceleration. The product line is ideal for aerospace, automotive and other industries that require high accuracy measurements and need to perform in-process gaging, often using custom fixtures. These versatile inductive probes can also be used individually on flat work pieces to perform comparative or flatness measurements or utilized for tasks like checking run-out on cylindrical work pieces.

Using the proprietary TESA Wireless Interface (TWIN) protocol, these Swiss-made probes offer enhanced stability during data transfer. The inductive probes can be incorporated into a handheld device, such as a bore or snap gage. The probes can also be attached to a measuring stand commonly found in quality control labs, where comparative measurements are taken using a setting master. With the absence of a connection cable, a wireless inductive probe provides total freedom of movement during the probe's translations and rotations around the part to be measured, especially on large components or assemblies. The instruments can be connected to the TWIN-STATION receiver, which manages and synchronizes up to eight wireless probes simultaneously.

"After three years of research and development, we are proud to announce the TESA inductive probes present a major technological leap in the field of metrology," said Marcel Bila, TESA group marketing director. "This product line will set a new standard with its distinguishing features: excellent repeatability, outstanding longevity and versatile usage. Manufacturers will find these wireless inductive probes to be indispensable tools for many of their toughest measurement challenges."

Related Glossary Terms

  • flat ( screw flat)

    flat ( screw flat)

    Flat surface machined into the shank of a cutting tool for enhanced holding of the tool.

  • in-process gaging ( in-process inspection)

    in-process gaging ( in-process inspection)

    Quality-control approach that monitors work in progress, rather than inspecting parts after the run has been completed. May be done manually on a spot-check basis but often involves automatic sensors that provide 100 percent inspection.

  • metrology


    Science of measurement; the principles on which precision machining, quality control and inspection are based. See precision machining, measurement.

  • quality assurance ( quality control)

    quality assurance ( quality control)

    Terms denoting a formal program for monitoring product quality. The denotations are the same, but QC typically connotes a more traditional postmachining inspection system, while QA implies a more comprehensive approach, with emphasis on “total quality,” broad quality principles, statistical process control and other statistical methods.
