Digital torque flange system for high dynamic force measurement and evaluation

The KiTorq system features an accuracy class of 0.05% and fully digital transmission, with a signal bandwidth of up to 10 kHz and integral speed measurement of 60 pulses per revolution, for maximum dynamic response and precision accuracy. The bearing and slip-ring free design of the Kistler KiTorq system consists of the Type 455x rotary torque measuring unit and the Type 454x stator torque evaluation unit. Units are highly robust and offer maintenance-free operation.

With choice of measuring range from 500 to 3,000 Nm, the rotor, which features a standard DIN ISO 7646 compliant flange configuration, may also be either purchased individually or as part of a fully calibrated torque measurement chain, together with a KiTorq stator. All KiTorq rotors capture torque measurement data using strain gages (gauges) (DMS), with their generated signal amplified and then processed at approximately 35 kSample.

This high-speed scanning rate means that widely dynamic torque parameters can be measured to high degrees of accuracy and repeatability.

The stator supplies frequency, as well as analog and digital signal outputs, while automatically detecting changes in the rotor and setting any required measurement parameters. Its open design allows for faster installation and protection from damage. Both rotors and stators within the KiTorq system with the same speed option may be used in any combination with one another. In addition, various calibration options are available for the configurable output signals of the KiTorq system. If an individual rotor or stator is changed, the notional calibration values may be calculated to avoid the user having to return the system for calibration. All calibrations are conducted within a high-precision calibration system that is fully traceable to recognized standards.
