Ultra high efficiency wireless MEMS acceleration sensor with integrated 9 DoF-IMU

‍

i4M's compact nemi G+ not only measures accelerations, but also rotation rates, rotation angles and magnetic fields in and around all three axes. With its integrated rechargeable battery, radio connection nemi Link 2400 and i4M's highly efficient technology, nemi G+ can be operated completely wirelessly for many hours. It is also suitable for permanent installations using its wide-range voltage input. Due to its robust design and easy mounting, nemi G+ is perfect for highly dynamic applications such as roller coasters, but also for rotating or moving components such as pitch bearings of wind turbines or gearboxes.

Ultra high efficiency telemetry module with integrated 9 DoF-IMU for connecting a variety of external sensors

‍

‍nemi DAQ is i4M's compact all-rounder in terms of Data AcQuisition.

Ultra high efficiency sensor node in i4M's Wide Area Monitoring System for connecting a wide range of external sensors

‍

nemi WAMS Node is the sensor node for data acquisition in i4M's Wide Area Monitoring System. In addition to the integrated humidity and temperature sensors, it offers connection options to measure strain, temperatures or distances.

‍

‍nemi WAMS was developed for applications that do not require high data rates but large area coverage with sensors and long battery runtimes. This is made possible by own highly efficient radio technology nemi Link 868. The elimination of cabling enables easy installation even on large assets and structures. Examples for use cases are climate or crack monitoring on bridges or continuous temperature monitoring on rolling bearings in big production facilities.
