The Hitachi Semiconductor Strain Sensor is a highly accurate, built-in torque sensor for controlling drive mechanisms in real-time. Conventionally, strain gauges or crystal piezoelectric devices have been used for torque measurements at the experimental level. However, because of their large size and low durability, it is difficult to integrate such devices into machines. It guarantees a high measurement accuracy (the error range is less than 1 percent), because it measures the shear strain of a rotating shaft directly.
This new Hitachi torque sensor, which won a 2016 R&D 100 award, utilizes a high-sensitivity sensing module, SSM10-001, so it is not necessary to redesign the drive mechanism including the shaft. Real-time control with high precision torque measurements is a constant problem in the machine industry. This new Hitachi torque sensor is intended to solve this problem. Data and power are transmitted between the rotating side and fixed side data in a non-contact manner.
Each year for more than 50 years, R&D Magazine has honored the 100 best innovations in research and development. We are currently accepting applications for the 2017 R&D 100 Awards. Innovators with an exceptional product developed between January 1, 2016 and March 31, 2017 should apply. Submissions close April 14, 2017
