DATAFLEX®

Torque measuring shaft

The principle: Torque measurement at low cost

Advantages

DATAFLEX® measures torques without contact or radio frequency, is maintenance-free and has a high frequency of response – all at low cost. Its secret is an innovative, patented measuring method. The newoptical – electronic light method senses the twisting of the torsion shaft and does not use wire strain gauges. The light is passed through 2 slotted disks and the transmission ratio of light changes proportio-nally to the torque as the disks rotate relative to one another.

All electronics are located in a stationary housing, so that neither data nor energy is transmitted from the rotating shaft.

The advantages? Accurate torque measurement with a band width of more than 15 kHz without maintenance wearing pickups.

Measured values for every torqueDATAFLEX® measures torques with a band width of more than 15 kHz and is therefore able to sense high frequency torque variations – such as the starting of an engine – precisely and continuously.

Easy analysis with standard appliancesThe analog output values are available both as voltage (0 ... 10 V) and current (4 ... 20 mA). They can be easily read with a multimeter or oscilloscope or easily analyzed by computer.

Maintenance-free – the whole life longDATAFLEX® does not require maintenance. The complete electronics are located in a stationary housing. Since neither data nor energy need to be transmitted from the rotating shaft,there is no maintenance of slip rings or expensive telemetry.

Two in One – control of torque and speedIn addition to torque measurement, DATAFLEX® also shows the speed. This feature is not an optional extra, but astandard part of the low cost package.

On site calibrationDATAFLEX® can be easily calibrated on site and includes fully automatic offset-balancing. Disassembly is not necessary. All connections are accessible via a standard multipole plug-in contact. An installed microprocessorcontrols the electronics.

Plug & Play: problem-free assembly Options to DATAFLEX® include KTR's RADEX®-N steel disk coupling and the servo disk RADEX®-NC coupling.The result? A compact, complete solution which can be quickly integrated into your product – and saves space!

Lucid interval – a ray of hope for designersDATAFLEX® measuring shafts supply precise results at low cost. Many machine control options are now practicalsuch as process control in agitator drives, extruders and worm drives, the control of coiling / lapping machines,shredders or boring mills, or in quality control.

DATAFLEX® torque measuring shafts are available for production use now!
