The product measures the absolute piston position. It is suitable hydraulic cylinders independent of length and diameter. The transducer determines the exact piston position and speed through high-resolution absolute measurement. For safety-related applications, the product is certified according to ISO 13849 PL d and IEC 61508 SIL2. it convinces by easy mechanical integration, without weakening of the piston rod. Additionally, the full effective stroke of the cylinder is available in the application.

The measurement range is specified up to 10 m with a resolution of 100 µm and a maximum pressure of 420 bar. The product comes in housing rated to up to IP69. The CANopen interface complies to CANopen Safety. It is available at an M12 connector. Liebherr shows the position transducer in hall 21 at stand A08 at the Hannover Messe 2017.
