Measuring flanges transmit torque without contact

An Industrial Measurements product story

The TMFA and TMFD are the latest torque measuring flanges from Industrial Measurements.

The TMFA and TMFD are the latest torque measuring flanges from Industrial Measurements.

The transducers incorporate strain-gauged beams and use noncontacting transformer coils to provide power for the strain-gauge bridge and receive the torque signal from the shaft.

Both transducers are available in ranges from 100 to 20,000Nm full scale, and will handle shaft speeds up to 12,000rev/min.

The TMFD which is the dual range version, is the transducer of choice if the application requires accuracy on the lowest scale of the transducer but may also feature torque "spikes".

By selecting the lower and then higher scale, both measurements can be made.

A lower scale is selectable at a good accuracy on either a 5:1 or 10:1 ratio.

The TMFD is particularly useful in test rig applications where alternating torques, torsional vibrations and unexpected peak torques can be a feature, for example, engine test beds, dynamometers, wheel load simulation, gearboxes and pumps.

Both devices have integral signal conditioning, providing a +/-5V output.

Options available include: speed measurement, +/-10V output, frequency output, flange to flange connection, RS232 interface and digital panel meters.
