Rotary Torque Transducers

With its compact, bearingless, maintenance-free design, the new TF Torque Flange Sensor from Magtrol brings many appealing advantages to torque measurement applications. The TF’s 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. Based on strain-gauge technology, the TF Sensor’s 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 ±10 VDC. Rotational speed can be measured and converted to a TTL output signal with the optional speed pickup. more info www.magtrol.com

This torque sensor is qualified for static and dynamic measurements on non-rotary applications. Further the measurement of reaction torques on rotating machine parts is possible. Especially the torque sensors with flanges are preferred. They are mounted between motor and stator, e.g. in agitator drives. This enables a maintenancefree torque measurement. For individual measuring tasks the design of our torque sensors can be adapted to the customer’s installation conditions. More application examples: Test structures in the field of precision mechanics Determination of friction torques Acquisition of breakage moments on screw caps The design has been optimized regarding overall length, weight and volume, so that axial forces up to relatively high limit values and bending moments of up to 20 % of the measuring range have only a small effect to the influence of the measuring element.

Rotary Transducer with Angle Measurement Option CheckStar sets the standard for dynamic torque and angle measurement of all continuous drive and impulse tools, with proven reliable performance in thousands of applications worldwide. CheckStar transducers fit in-line between the assembly tool and the fastener, measuring the actual torques applied under production conditions. Whatever the vibration and shock loads experienced, CheckStar's patented contact system ensures contact is always maintained between the readout and the strain gauges. Inferior systems suffer from "brush bounce" that leads to unreliable torque readings. The low inertia design of CheckStar ensures accurate and repeatable measurement of high speed transients, such as the point of shut-off on continuous drive tools and the pulsing of impulse tools.
