3 TORQUE MEASURING TECHNOLOGY TYPES AND OPERATING DESCRIPTION Properties of torque measuring shafts 16, 32, 42, 70 - High precision with each revolution For legend of pictogram please refer to fl apper on the cover NEW With the new size of 70 KTR extend their range of precision measuring shafts for bigger torques. Along with the well-established sizes of 16 to 42 measuring ranges from 10 Nm to 5000 Nm are covered now. With the new series the torque is measured using the approved technology of wire strain gauges DMS while processing without contact with a revolution of 24 bit. Thus, the inaccuracy of torque measuring is reduced to less than 0.1 % of the measuring range. By integrating a high-resolution speed sensor the new series combines four measurements in one: Measuring the torque, speed, rotation angle and rotation direction is part of the standard equipment. 85, Patented technology at top prices The torque measuring shafts sizes 85 and 140 measure the torque without contact and free from wear. Their secret is a patented measuring method sensing twisting of the torsion shaft by light quantity measurement. Here the light is directed through two disks the transparency of which changes proportionately to the torque. The overall electronics are installed in a stationary housing to make sure that no signals have to be transmitted by the rotating shaft and the torque is available completely with a high band width of 16 khz. This allows to measure and analyze highly dynamic processes accurately. The analog output values are available both as a voltage signal from 0-10 V and as a current signal from 4-20 ma. In addition a speed encoder is fi tted as a standard providing a signal at a resolution of 60 pulses per revolution. Couplings adjusted to every application Matching with all series of we recommend to use the servo lamina coupling RADEX -NC and the steel lamina coupling RADEX -N. Together they form a compact solution which is easy to integrate while having a high stiffness. Basically it is also possible to use backlash-free, plug-in types of couplings such as ROTEX GS or to fi t an overload coupling. 310

The following features save the purchase of expensive measuring amplifi ers and converters: The torque output can be filtered over 5 steps so that short torque peaks in the display can be reduced. The pulsed outputs of the speed signals can be configured both for 5V (TTL) and 24V (HTL). This makes the outputs compatible with data logging boards and SPS controls. In parallel with the pulse signal an integrated frequency voltage converter supplies a DC voltage from 0 10 V proportionally to the speed, the scaling of which can be adapted individually. This makes an expensive counter superfluous so that the signal can either be processed as a voltage or displayed. A direction signal indicates the rotational direction of the drive (with 16, 32, 42 and 70). 311 Torque measuring technology
