Regardless of whether lifting platforms, mobile cranes or self-concrete pumps, mobile machines must always function as smoothly, precisely and efficiently as possible. Smart sensors are in demand here that reliably detect the complex movements of the machines. To achieve these goals, Siko has introduced the wire-acutated encoders of the “Pure.Mobile” family, a new range of encoders (a key component in load monitoring systems to precisely determine the position of the support and the telescopic mast) recently launched by the German company on the market.
The central components of the Pure.Mobile series are wire-actuated encoders of the type Sg31 and Sg61, which have a maximum measuring length of 3 to 6 meters. By integrating the latest generation of inclination sensors, they combine not only the detection of position and speed, but also the measured value of inclination. The two integrated inclination sensors are complemented by the large variants Sg121 and Sg150, which offer a maximum measuring length of 12 or 15 meters.
The integrated single-axis inclination sensor is available as an option and measures inclinations in the range of ±180 degrees with a resolution of up to 0.001 degrees and an accuracy of ±0.2 degrees. In this way, the sensor also detects small deflections. Its integrated temperature compensation keeps the values stable over the entire measuring and temperature range. The sensor data are transmitted to the controller via CANopen, CANopen Safety or SAE J1939 interface, independent of the position value.
Thanks to the modular sensor design, the inclination detection can be integrated into any Siko wire-actuated encoder without changing the design and size or connection type of the sensor. With an increasing range of functions, installation space, assembly effort and product costs on the machines can be reduced.
All “Pure.Mobile” sensors have been developed according to the requirements of mobile machines and are extremely robust. This includes an E1 approval from the German Federal Motor Transport Authority as well as high EMC, shock and vibration resistance. The sensors are installed in compact housings and always provide reliable and precise values, even under harsh environmental conditions.
