Vibration measuring technology - Import export

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 sensor, a controller unit and the output interface PROFIsafe over PROFINET for output of the acceleration values. Thanks to its high resistance to vibration and shock - more than the defined measuring range -, the sensor is suitable for use in areas with rough environmental conditions.Electrical connection is carried out using three connectors.

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 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 sensor, a controller unit and three types of output interface. The main feature is two safety switching contacts (potential-free), which can be used e.g. in the safety chain to undertake safety shut-off in the event of excessively high acceleration values. Data output is carried out via the CANopen interface. The standard or the safety profile can be selected. There are additionally two analogue outputs 4 ... 20 mA, which can be optionally assigned to two of the three measurement axes. Thanks to its high resistance to vibration and shock, the sensor is suitable for use in areas with rough environmental conditions.
