The Strengths of Ono Sokki

Advancing Manufacturing with the ​Power of Measurement
​

We have been developing and manufacturing measuring instruments and testing equipment for over 70 years.
​

Inhering the spirit of its founder, Gichiro Ono, Ono Sokki  has been contributing to take on challenges to create  what society needs—things that no one has ever attempted before.​
Through measurement and sensing technologies, we strive to solve a wide range of social challenges.

Three strengths

  • Expertise

    Advanced Measurement Technology That Supports the Foundation of Manufacturing ​

    ​On both axes: "actual measurement" and "calculation" Solving our customers' problems.

    In the manufacturing field, particularly in the automotive industry, Model-Based Development (MBD) is being utilized. Ono Sokki supports the core of new development methods like MBD by combining high-precision model generation and calculations (simulations) based on reliable measurement technology with validation through actual measurements.

    Cases

    Ono Sokki has established a method for estimating the forces applied to a car's body through the suspension, based on actual measurement results from TPA (Transfer Path Analysis), utilizing their expertise in acoustic and vibration measurement technology. This has clarified whether vibration countermeasures should be implemented on the suspension or the body, improving development speed. Through vibration countermeasures, it contributes to enhanced comfort during driving and reduced environmental impact.

    Exploring all possibilities and providing the optimal solution.

    The environments in which measuring instruments are used vary greatly, including the presence or absence of temperature changes, vibrations, shocks, and changes in atmospheric pressure.

    Cases

    In rocket development projects, rotation sensors that are capable of being installed in harsh environments with extreme temperature differences and possess safety features are used in fuel pumps to achieve high precision. In power plant projects, rotation sensors that can be used in the special environment of oil are being developed. Many domestic power plants have Ono Sokki's rotation sensors installed. The long-selling rotation sensors will continue to meet the demands for stability, durability, and reliability.
