The concept is so modular and versatile that customized OEM products can be rapidly developed. CEDRAT TECHNOLOGIES offers an innovative solution for contactless torque measurement. The concept is based on the use of a torsion converter and a proximity sensor. The nominal sensing solution relies on a new PCB based Eddy Current Sensor (ECS) developed by CEDRAT TECHNOLOGIES. The contactless torque sensor (CTS) can be provided with a digital signal processing software and a compatible electronic card. > ADVANTAGES • Cost-effective modular approach • Ease of integration • Solid state design • Stationary axle or rotating shaft • Working in harsh environment (dust or sand, oil, water) • Reliable measurement • Compatibility with all types of shaft materials • Possible torque measurement at zero speed • Angle and speed measurement (options) > APPLICATIONS IN: • Production Process Monitoring • Power plants • Wind-electric power stations • Automotive (steering, gearing...) • Drilling systems • Textile machines • Mechanical conveying technology • Household appliances • Step-Over Electric Bikes • And much more > CONCEPT A torque applied on a shaft naturally generates a torsion deformation of the shaft. The CTS is designed to measure this torsion. This measurement is performed by 2 sub systems:

The converter transforms torsion deformation into linear displacement detected by a proximity sensor (Fig.3). In another terms, the converter (Fig.4) transforms angular shift into significant axial shifts of two targets in a direction along the shaft axis. The torsion converter can include a shaft (Fig. 1) or be located onto an existing shaft (Fig.2). The shaft can be a...
