3-axis accelerometer RAM900

vibratingcapacitiveMEMS

RAM900 Accelerometer is an acceleration sensor independently developed by Rion Technology to detect vibration and shock. It provides accurate acceleration for the control system through CANopen or analog interface. The selected capacitive MEMS sensor has the highest operating accuracy, especially at small amplitudes, where measurement errors due to cross-axis sensitivity are negligible. Therefore, the RAM900 is ideal for the precise acquisition of vibration, such as vibrations on wind turbine towers. Even if the accelerometer is mounted on a solid load-bearing machine part, measurement distortions caused by vibrations can still be excluded. The RAM900 uses a 4th-order low-pass filter to effectively suppress spurious frequencies, such as those caused by yaw brakes in wind turbines. Not only effectively compensates for offsets caused by installation errors or temperature drift, but also significantly improves accuracy. (Configurable: safety relay outputs can be integrated in any safety system and are activated when specified default limits are exceeded). Four factory-configured frequency bands with different filters can be fine-tuned according to the requirements of specific equipment types. For wind turbines, the RAM900 accelerometer is ideal for implementing the safety function "excessive shock and tower vibration protection". Long-term monitoring can prevent damage or even destruction of equipment. ▶ APPLICATION ★ Wind power turbine
