HERMETICALLY SEALED TORQUE TRANSFER STANDARD WITH EXTREMELY LOW PARASITIC SENSITIVITY

P. D. Hohmann, H. Gassmann

Abstract

A new design of strain-gauge torque transducer has been developed which is hermetically sealed and especially suitable for low nominal torque capacities. Apart from high basic repeatability, the major design aim was a high degree of insensitivity to parasitic forces and moments. In order to fulfil both requirements, a sensing element shaped as an elastic hinge was chosen. Theoretical considerations and measuring results confirm the characteristics which were aimed to be achieved. The particular design and the metrological performance make the new sensor ideally suited for applications as reference transducer and torque transfer standard.
