Stress-controlled rheometer: Combined motor-transducer system. (M = torque; φ = deflection angle; n = rotational speed) In a controlled-stress (CS) rheometer, the torque acting in the sample is determined directly from the electrical torque generated in the motor. With such a design, no separate torque sensor is required.
A torque tester is a quality control device to test or calibrate torque-controlled tools.This includes electronic torque wrenches, click torque wrenches, dial torque wrenches, electric screwdrivers, air screwdrivers, pulse tools, cordless screwdrivers, nutrunners, and torque screwdrivers.
Rotary encoders are used in a wide range of applications that require monitoring or control, or both, of mechanical systems, including industrial controls, robotics, photographic lenses, [2] computer input devices such as optomechanical mice and trackballs, controlled stress rheometers, and rotating radar platforms.
Torque measurement is somewhat complicated since there are two machines in tandem - an inline torque transducer is the preferred method of torque measurement in this case. An eddy-current or waterbrake dynamometer, with electronic control combined with a variable frequency drive and AC induction motor, is a commonly used configuration of this type.
Another use is to transmit the signals from rotary torque sensors installed on electric motors, to allow electronic control of motor speed and torque using feedback. Because they are transformers, rotary transformers can only pass AC, not DC, power and signals. The supporting electronics, including the tape heads or torque sensors, must be ...
