We have developed special sensor materials that allow our non-contact displacement sensors to minimize temperature drift and realize long-term stability. Moreover, our sensors offer superb environmental durability in the face of harsh conditions that include both high and low temperatures as well as high pressures.
We have accumulated a sizable track record by customizing these devices precisely to match our customers' needs and usage environments. The applications have ranged from monitoring production equipment and product quality control to use in laboratory and research settings. These products have contributed to society in settings and fields that include the cutting-edge space industry, to automobiles, to such mission-critical parts of the social infrastructure as railways, to the factory floors of the manufacturing industry.

  • Aerospace

    Our products have been adopted as shaft vibration and axial position sensors for the liquid hydrogen and liquid oxygen turbo pumps on rocket engines, where pressures are high and the temperature characteristics range from ordinary temperatures to the extreme lows of -253°C. These systems collect data on shaft vibration and axial positions from the engine development stage to the engine tests that are performed just prior to launch.

  • Automobile

    Thanks to their stability and the repeatability of their results under a wide range of operating temperatures, our sensors have been adopted for measuring oil film on automobile crankshafts and the thickness of rubber sheets in the manufacturing process. These parts may be small, but in an industry where all parts and machinery are directly linked to the driver’s safety, people have enormous trust in our technology.

  • Railway

    Our sensors are used on railway inspection cars, which maintain the safety of bullet and other high-speed trains. They measure the tracks and the irregularities in track alignment (lengthwise bumps on the rail track surface) that influence travelling performance.
    The maglev linear motor cars that made their first operational run in Japan in 2005 also use our sensors in their levitation control systems. These systems keep the train operating efficiently by preventing accidental contact while adjusting the gap between the car and the rail when levitating to the minimum appropriate level.

Other Areas

Our sensor technology is suitable for a broad range of fields Measuring displacement, thickness, and configuration, as well as vibrations and eccentricity
