A torque measurement transducer system

A torque transducer system is described that measures the force of reaction on the stationary member of a rotating machine delivering or receiving power. The system is not interposed between the driver and the driven machine but is used as a subbase in setting up the machine whose torque is to be measured. The transducer has a torque rating but no speed rating. Its torque rating can be changed by interchanging sets of hollow cylindrical springs. Some data are given to show its versatility, and economies in time and capital costs
