Registration of inclination in the gravitational field by means of MEMS sensors (Micro-Electro-Mechanical-System) with subsequent digitisation and linearisation via controllers. MEMS sensors are integrated circuits manufactured using silicon bulk micromechanical technology.
Double capacities are formed with the aid of moveable micromechanical structures. If these structures are deflected in the case of acceleration, e.g. gravitational acceleration (g), this results in capacity changes, which are registered and further processed using measuring technology. The output voltage follows the function U ~ g * sin α. In this case, the angle α is the sensor’s inclination angle measured against the g-vector. These sensors measure precisely, have a long service life and are very robust. The measuring axes operate independently of each other.
The Profinet interface according to IEC 61158 / 61784 or PNO specifications order No. 2.712 and 2.722, version 2.3, is integrated into the inclination sensor series NBT.Real time classes 1 and 3 are supported, i.e. Real Time (RT) and Isochronous Real Time (IRT) plus the requirements of conformance class C.The integrated 2-fold switch enables the TWK PROFINET inclination sensor to be used in star, tree and line network topologies.
