Bearingless Torque Measuring Shaft

The classic torque measuring shaft, as often used in test benches, presents numerous challenges. It is usually mounted on bearings and often equipped with slip rings, which leads to increased wear and undesirable force shunting. In addition, mounted measuring shafts require a bearing block and elastic couplings on both sides, which makes test bench operation more complex and less efficient. The bearing noise is also particularly disruptive and can be problematic in sensitive test applications.

The MANNER torque measuring shaft is based on state-of-the-art sensor telemetry. The torque signal is recorded using strain gauges and digitized by a high-precision measuring amplifier mounted on the shaft. This operates with a resolution of 16 bits and enables contactless signal transmission via an antenna gap of up to 10 mm. This means that installation remains unproblematic both radially and axially.

The bearingless torque measuring shaft from MANNER Sensortelemetrie offers a superior alternative here. By eliminating bearings and couplings, not only is the test bench design more compact and economical, but the measurement accuracy is also significantly improved.

Sensor Telemetry

The core task of the sensor telemetry system is the contactless data transmission based on a high-frequency electromagnetic field. The rotating part, in most cases inductively fed by the HF field, is used for this purpose. This means that the complete rotating part, consisting of the sensors, the measuring amplifier and the rotor antenna are supplied inductively.

This and the fact of contactless data transmission makes our sensor telemetry maintenance-free!

The stationary part of the sensor telemetry system generates the HF (High Frequency) field and establishes the coupling with the rotating part. The data transmitted via the high-frequency field are modulated onto the carrier frequency of the HF field and are decoded by the evaluation unit where they are available as a digital data stream.

The XtreMA high-precision torque transducers impress with their exceptional accuracy. The standard flange series is specified with an accuracy class of 0.05 .

The extended version offers even more accuracy with a class of 0.01, making it ideal for high-precision measurement requirements.

Maximum speed capability for electric motor test benches.

For test benches used in electromobility, maintaining stability at extremely high speeds is essential.

The innovative MANNER design meets this requirement with an impressive speed stability of up to 32,000 rpm . This makes the torque transducers perfectly suited for high-speed applications.
