KiTorq Torque Measuring Flange from Kistler for Testing Motors, Engines, Pumps and Transmissions

Flexible and Maintenance-free, Precise and Digital: The new KiTorq Torque Measuring Flange from Kistler for Testing Motors, Engines, Pumps and Transmissions

Kistler Group: By designing a measuring unit and an evaluation unit as separate assemblies, and introducing modular combinations achieving extremely high measuring accuracy, the new KiTorq system torque measuring flange from Kistler allows test rig owners previously unknown flexibility in measuring torque.

The system consists of a measuring unit (rotor) Type 4550A... and an evaluation unit (stator) Type 4541A… . As the rotor has a standard configuration to ISO 7646 for transmission flanges, it is compatible with all common test environments and offers a choice of measuring range: 500, 1 000, 2 000 or 3 000 N∙m. Rotors of different sizes can be combined with the same ring-less stator for particular easy installation. They can also be used to test different assemblies without having to completely modify the test unit. The open stator design makes installation quicker while protecting against damage, and facilitates visual inspection during testing.

The stator supplies frequency as well as analog and digital signals. All signal outputs are fully scalable via RS-232C or USB. Whatever the rotor's original setting, the user can accommodate any testing task by deciding the measuring range in which the full output signal is to be available. It is also possible to define and output freely selectable second measuring ranges at each output. There are several calibration options available for the configurable output signals of the KiTorq system. If an individual rotor or stator is replaced, the notional calibration values can be calculated to avoid any need for the user to return the unit for calibration.

As a system, the KiTorq with fully digital transmission offers an accuracy of 0,05 % and a signal bandwidth of up to 10 kHz with maximum dynamic response and precision. A speed sensor with 60 pulses per revolution is already incorporated in the standard model.

The solid measuring flange is extremely robustly designed and the contactfree signal transmission means it operates without maintenance. It has been tested to EN 60068-2-27 for mechanical shock, to EN 60068-2-6 for triaxial vibration loading and to EN 61326-1 for interference immunity. The measuring flange is ideal for use in test rigs for electric motors and internal combustion engines, transmissions, pumps and compressors in automobile, power station and power transmission, mechanical, medical and process engineering.
