1 DATAFLEX Torque measuring shaft DATAFLEX 263

The principle: Torque measurement at low cost DATAFLEX measures torques without contact or radio frequency, is maintenance-free and has a high frequency of response all at low cost.

The light is passed through 2 slotted disks and the transmission ratio of light changes proportionally to the torque as the disks rotate relative to one another.

3 The principle: Torque measurement at low cost 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 new optical 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 proportionally 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. ADVANTAGES Measured values for every torque DATAFLEX 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 appliances The analog output values are available both as voltage ( V) and current ( ma). They can be easily read with a multimeter or oscilloscope or easily analyzed by computer. Maintenance-free the whole life long DATAFLEX 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 speed In addition to torque measurement, DATAFLEX also shows the speed. This feature is not an optional extra, but a standard part of the low cost package. On site calibration DATAFLEX 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 microprocessor controls 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 designers DATAFLEX measuring shafts supply precise results at low cost. Many machine control options are now pratical such as process control in agitator s, extruders and worm s, the control of coiling / lapping machines, shredders or boring mills, or in quality control. DATAFLEX torque measuring shafts are available for production use now! DATAFLEX 265
