The Kistler KiTorq torque sensor system is now available with Profibus, Profinet CANopen, Ethercat and EthernetIP interfaces in addition to the analogue/frequency, USB and RS-232 interfaces. The new stator is fully compatible with all KiTorq type 4550A rotors. The new communication options allow the KiTorq system to be integrated directly into the user's test environment through the fieldbus interfaces. This saves time during installation and eliminates the cost of additional equipment to convert measured data, making the new KiTorq stator very cost effective for test stand design, installation and operation in applications for electric motor, internal combustion engine, transmissions, pump and compressor testing.
Kistler's new stator can be used with any KiTorq rotor of the same speed rating and will automatically recognise the rotor measuring range. With rotors available with seven measuring ranges from 100 to 5000Nm, hardware investment is minimised as one stator may be used with rotors of differing ranges for different applications. Installation is simplified by the contactless, digital telemetry that eliminates the need for an antenna ring whilst maintaining the excellent signal bandwidth of 10kHz and accuracy of better than 0.05 per cent of range. A speed measurement of 60 pulses per revolution is integrated in the standard system.
