Capacitec, Inc. has announced the successful application of high-temperature non-contact displacement sensors within disc brake wear analysis, glass manufacturing and aircraft engine testing applications. Since the 1970’s, Capacitec high temperature non-contact sensing technology has been in use in North America, Europe and Japan to solve the most demanding applications, measuring displacement of up to 0.4” (10 mm), within extreme temperature environments where resolution of one micron or better is a requirement, such as:
• In-vehicle disc brake wear analysis. Capacitec Model HPC-150C-H sensor assembly offers small size (OD 9.5 mm), large range (2.5 mm) and 0.25 micron resolution. Operating at +400 °C, they are used to test runout, thickness variation, coning, wobble and thermal expansion of disc brake rotors.
• Automotive windshield glass production. Manufacturing equipment incorporates Model HPC-500-V sensors with flexible high temperature cables. These measure gaps in the tooling at production temperatures of +800 °C, to ensure precise glass size and shape specifications.
• Commercial plate glass production and fabrication. Capacitec custom gap sensors with 4 meters of +800 °C high temperature cables are used to control thickness of anti-reflective and solar coatings.
• Aircraft engine testing. Operating in temperatures of up to +1,000°C, Capacitec Model HPC-75-V/S non-contact displacement sensors measure thermal expansion, axial expansion and radial runout to confirm that dimensional design parameters meet specification at extreme operating temperatures
