Being a scalable measurement system, the STS can be perfectly tailored to the hollow shaft diameter of the application. Device variants in one of seven standard internal diameters of 30 mm to 230 mm are available for this purpose. With these standard sizes, the system covers the typical diameters of commonly used industrial direct drives. In addition to this, custom diameters for millimeter precise installation up to a hollow shaft diameter of 500 mm can be implemented. The design of the read head can also be tailored to the customer’s requirements, thereby enabling the STS to be integrated into even the tightest installation spaces. Thanks to the flexible technology, two different motor concepts are supported: internal rotor motors as well as external rotor motors – the choice is yours with the STS.
