The recently developed Dataflex 16 extends the existing range of contactless torque measuring shafts and is available for measuring torque ranges of 89 [lb‑in], 266 [lb‑in] and 443 [lb‑in]. The torque is measured using well‑approved technology of wire strain gauges combined with the latest electronic components. The torque signals are processed without contact at a high resolution of 24 bit achieving an accuracy of 0.1%. Supplementary to torque measuring the size 16 has a speed encoder providing two offset impulse with a resolution of 360 pulses per revolution. The Dataflex torque measuring shafts sizes 22 to 140 measure the torques without contact and free from wear. Their secret is a patented measuring method acquiring the twisting of the torsion shaft by measuring the quantity of light. For that purpose the light is directed through two disks the transparency of which is amended proportionally to the torque. The overall electronics are situated in a stationary housing to make sure that no signals have to be transmitted by the rotating shaft and the torque is available accurately with a high band width of 16kHz. This can measure and analyze highly dynamic processes accurately. The analog output values are available both as a voltage signal from 0‑10V and as a current signal from 4 ‑ 20 mA. In addition, a speed encoder is integrated providing a signal at a resolution of 60 impulse per revolution.
