Torquemeters


Combine the high accuracy and low noise of Astech Rotary Telemetry Transmitters with torque sensing strain gauges provide a torquemeter having excellent performance.  Applied to existing shafts both mean torque and torsional oscillations up to 30KHz may be measured without disturbing the dynamics of the components under test.  Alternatively the torquemeter can be supplied in the form of a "drop in" coupling custom manufactured to suit as existing application.  Simple, accurate and inexpensive.

Very low levels of torque and thrust need to be measured in this torqueshaft which forms the head of a scale model test rig for marine propeller.

Torque measurement system attached to 240mm diameter coupling to form torquemeter for ship's trials.  The battery powered transmitter extends transmission air gap to 150mm, making installation very straight forward.
