Square Drive Static Torque Transducer | DTD-S
High Accuracy, Easily Adaptable, with a Square Drive Shaft
The DTD-S series of reaction / static torque transducers have a square drive and are primarily used to measure the fastening or breakaway torque of bolts and nuts. The square drive static torque transducer is ideal for calibrating automated torque screwdrivers, spanners and wrenches.
We are able to offer custom drive sizes and configurations to suit your application if required, and can also offer versions with improved sealing up to IP68 for applications where operating conditions are harsh or involve submersion.
