Inductive Position Coding System (PCI)

Rotary joints or slewing bearings track large objects such as wind turbines or solar panels for optimum wind or sun direction; in marine engineering and port systems technology, large loads are moved via the pivot joint of a crane boom. Here, the new inductive position coding system (PCI) accurately records the movements to optimize the processes, saving time and energy.

The position coding system detects several steel pins along a code rail and calculates the absolute rotation angle position of the bearing. The exact position is available without a reference run after switching on the inductive position coding system, which is an advantage during intermittent operation or after maintenance work.

Designed for a bearing diameter of 0.5 m - 4 m, the coding system provides an absolute angle resolution of 0.24° - 0.03°. Depending on the required measurement accuracy, angular speeds between 3 °/sec and 12 °/sec are attainable. The structure of the inductive position coding system enables both mechanical adaptation to the specific customer application as well as modification of the data interface.
