  1. General Details

    Reference torque transducer TB1A: For small space requirements up to 69 millimeters

    The TB1A reference torque transducer is very flat with a maximum width (depending on the measuring range) of 69 millimeters and is therefore, is ideally suited for torque measurements in restricted space conditions. In addition, the drive shafts can lead axially through the torque sensor, thanks to the central bore. Due to itsthe compact design, the transducer is very well- suited for use in testing machines or as a reaction torque sensor with the direct coupling of the  drive motor or transmission.

    Owing to its flat design, the TB1A has a very high stiffness in all directions and is the compact alternative to the extremely precise reference torque transducer TB2.
