The new Kistler KiTorq torque measuring flange system operates without an antenna ring and has standard flange geometry conforming to ISO7646 for easy installation. The open stator design allows faster installation whilst minimising the risk of damage and easier visual inspection during testing. The universal, intelligent stator may be used with any KiTorq rotor of the same speed rating for greater operational flexibility. A choice of 500, 1,000, 2,000 or 3,000 Nm measuring ranges is available each with an accuracy class of 0.05% of range. The system has an excellent torque signal bandwidth of up to 10 kHz and a 60 pulses per revolution speed output.
A single, intelligent stator can be used with any KiTorq rotor of the same speed rating and will automatically recognise the rotor measuring range. This minimises hardware investment as one stator may be used with rotors of differing ranges for different applications. Installation is simplified by the contactless, digital telemetry that does not require an antenna ring. The lack of an antenna ring has not reduced the precision of the sensor which has an excellent signal bandwidth of 10 kHz and accuracy of better than 0.05%.
The stator supplies frequency, analogue and digital signals outputs that are fully scalable via an RS-232 or USB interface. When needed, the rotor’s original measuring range may be overridden to allow the full output signal to be available over a defined range. A second, freely selectable measuring range may also be defined at each output.
