Registration of inclination in the gravitational field by means of MEMS sensors (Micro-Electro-Mechanical-System) with subsequent digitisation and linearisation via controllers. The housing-based inclination sensor (model NBN 65) has a stable aluminium housing (optionally stainless steel) and is highly-resistant to vibration and shock.
One or two connectors/socket in the case of CANopen can optionally be selected for connection. Casting measures in the housing lead to the achievement of protection class IP 69K, e.g. for use under water. 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 NBN has a redundant MEMS sensor system. Data output is carried out via the CANopen interface by means of the object SRDO (Safety Relevant Data Object). Normal and bit-inverted.
