Description

Applied Measurements Torque Measurement System is a complete, portable torque testing system.  It is supplied ready calibrated, to UKAS-traceable standards, with a high-resolution digital meter, enabling you to undertake fast, portable, torque testing and monitoring.

The reaction / static torque transducer DTD-S has a square drive and is designed to measure the fastening or breakaway torque of bolts and nuts. Plus, this torque tester system is ideal for calibrating automated torque screwdrivers, spanners and wrenches.

Thanks to the high accuracy of the static torque transducer of better than ±0.1% of rated capacity, our torque meter systems are perfect for the calibration or testing of torque tools in a QA environment.

The torque meter system has an IP65 dust-tight and splash-proof protection as standard making it suitable for most industrial environments. What’s more, the torque transducer can be customised with improved sealing up to IP68 submersible for applications where operating conditions are harsh or involve long-term submersion.

The torque meter system comes with a high resolution 128 x 64 monochrome dot matrix display and is protected to an IP64 dust-tight, splash proof rating.  It features peak & trough capture and display hold/freeze options.

The digital meter’s six range capability means it can be calibrated to work with up to six different sensors if you need to cover a range of different torque levels, although please note that due to the fact that there is only one cable input, only one sensor at a time can be monitored.

Need an integrated torque meter and display? Try our DRBK-A Low Cost Rotary Torque Sensor with Display which features a built-in 4 segment LCD display giving you instant torque and speed readings with real-time speed updates of 1x sample/second and torque updates of 1,000 sample per second.
