New torque sensor has magnetoresistive built-in speed sensor and integral, digital measurement conditioning system

For highly dynamic measurements the cut-off frequency of 10kHz may be user customised by an integrated, digital, low-pass filter and the second measurement range can be flexibly scaled up to 1:10 or 1:5 of the rated torque. The new, fully scalable magnetoresistive speed and angle measurement system has a pulse frequency to 8192 pulses per revolution, with twin tracks displaced by 90° to provide clockwise and anticlockwise indication. A reference pulse is also available.

The fully digital, contactless signal transmission delivers a standard accuracy of 0.05% with ± 0-5/10 V DC signal outputs, an RS-232C serial data output and a USB interface.

The new, robust design is suitable for use in oil mist and other contaminated environments and overload protection of the lower range is said to ensure reliable measurement with the greatest possible dynamics and accuracy in the most demanding industrial applications. The IP40 protection and anodised aluminium housing minimise routine maintenance needs in real world production applications.
