With its compact, bearingless, maintenance-free design, the new TF 300 Series Torque Flange Sensor from Magtrol brings many appealing advantages to torque measurement applications. The TF\u2019s high torsional rigidity supports direct mounting on the machine shaft or flange, avoiding the use of couplings on one side. This allows easy integration into a test system, shortens the overall length of the test bench and reduces costs.<\/p>\n
Based on strain-gauge technology, the TF 300 Series Sensor\u2019s precise telemetry system enables highly accurate signal transmission. A signal amplifier mounted in the measuring flange amplifies the measuring signal, modulates it to high frequency and transmits it inductively (via the HF transmitter) to the receiver. In the receiver, the digitized torque signal is transformed into an analog output signal of \u00b110 VDC. Rotational speed can be measured and converted to a TTL output signal with the optional speed pickup.<\/p>\n
The contactless design of the Torque Flange Sensor permits a gap of up to 5 mm (typically 1 to 3 mm) between the rotor antenna and HF transmitter, which makes the signal acquisition insensitive to any axial or radial misalignment. Another advantage of this torque measurement system is its insusceptibility to signal interference\u2014due to the fact that, unlike other designs, the antenna does not need to be looped around the sensor. Additionally, a protective cover can be mounted close to the sensor with no effect on the signal.<\/p>\n
