Force and Torque Sensor | 2-Axis | Bi-Directional | DBBSS/TSF


Applied Measurements DBBSS/TSF dual axis force and torque sensor is a compact and accurate transducer designed to measure both static torque and axial load in clockwise and counter-clockwise / tension and compression respectively.

The unique design of the 2-axis force and torque sensor ensures that crosstalk between the axes is minimised, with less than 1% being typical, whilst maintaining an excellent accuracy of better than 0.1% of rated capacity in both torque and force modes.

Applied Measurements DBBSS/TSF 2 axis force and torque sensor series is used widely in the geotechnical and materials testing sectors where it is employed as a central component on pieces of high accuracy analytical test equipment, although its design lends itself to a huge range of other applications where dual-axis measurement is required.

The nature applications where the 2 axis force and torque sensor may be used is likely to require customisation in terms of size, capacity and the configuration of mounting holes or fixtures, and so we are pleased to say that design modifications to fit the DBBSS/TSF to your application can be offered with little or no effect on cost.
