High-precision vibration displacement measurement is possible!
This is a device that can measure changes in displacement and vibration quickly and non-contact by irradiating light onto the measurement target through optical fiber and detecting the reflected light. Since it uses light for measurement, it does not impose any load on the measurement target and is not affected by magnetic or electric fields. Additionally, the interchangeable sensor module can be replaced or selected according to the required sensitivity, measurement range, frequency band, and spot diameter. The "PM-E," which pursues miniaturization and simplicity, is a product that meets a wide range of demands in research and development as well as various industrial fields.

Company information
Unipulse Corporation is a sensor manufacturer. We develop a wide range of products using various technologies, including digital indicators for optimal load application in press-fitting and crimping, capacitive non-contact displacement meters, spindle clamping force measuring devices, small-diameter tool gripping force gauges, and rotating torque meters. In particular, the UTM series of rotating torque meters has become the standard for shaft-type torque measurement and is used in many development and manufacturing sites. In recent years, we have internalized the production of strain gauges and are manufacturing load cells and multi-force gauges in-house. Our subsidiary, Robotech, develops and sells products such as Uniservo (electric torque actuators) and Moonlifter (electric balancers). Notably, the electric balancer, which constantly detects force and position using load sensors and servo motors, allows for the movement of heavy objects with the sensitivity of human hands. We have received much positive feedback due to its unprecedented ease of use. Moving forward, the Unipulse Group will continue to prioritize research and development, delivering products that are first in Japan and the world.
