The sensor system is intended as a component for use e.g. in wind power plants to measure and evaluate vibrations in the mast head. Registration of dynamic accelerations by means of MEMS sensors (Micro-Electro-Mechanical System) with subsequent digitisation by a controller. The device consists of an acceleration sensors, a controller unit and three types of output interface. Data output is carried out via two analogue interfaces with 4 ... 20 mA plus CANopen and via 4 relay contacts (currently 1 error relay contact). The NVA is parameterised via the CANopen interface. This is not galvanically separated. The sensor is equipped with a filter circuit to protect against fast transients and surge voltages of up to 2 kV in the supply. The protection types are IP 69K (housing) and IP 67 (connector/socket). With its good vibration and shock values, the sensor is suitable for use in areas with rough environmental conditions. The vibration sensor is equipped with a stable aluminium housing (optionally stainless steel). Elongated holes are available for mechanical alignment (up to approx. ± 7.5°). Electrical connection is carried out using two connectors or two cables.
