nemi G+ is a compact, high-precision wireless measurement sensor designed for advanced monitoring of accelerations, vibrations, rotation rates, rotation angles, magnetic fields, and temperature in and around all three spatial axes. As part of the nemi® Wireless Measurement Family, it represents a powerful all-in-one solution for demanding industrial and research applications where cabling is impractical or impossible.

The sensor integrates a high-resolution, low-noise capacitive MEMS accelerometer, a triaxial gyroscope, a triaxial magnetometer, and an internal temperature sensor in a robust and lightweight housing. This sensor fusion enables precise inertial measurement (IMU) and vibration analysis even under extreme dynamic loads.

With its integrated rechargeable battery and proprietary nemi Link 2400 radio technology developed by i4M, nemi G+ operates completely wirelessly while maintaining excellent data integrity and long battery runtimes. Depending on the configuration, the device supports continuous measurements from several hours up to multiple weeks.

nemi G+ supports both live transmission of raw measurement data and smart data generated directly on the device via edge computing, significantly reducing data volumes and communication costs. For permanent installations, the sensor can also be powered via a wide-range DC input (8.5–28 V), ensuring uninterrupted operation.

Thanks to its small dimensions, low weight, and easy mounting, nemi G+ is ideal for applications such as:

• Online condition monitoring of roller coasters

• Dynamic behavior analysis of rotating machinery

• Monitoring of wind turbine pitch bearings

• Gearbox and drivetrain vibration analysis

• Measurement of physical loads on the human body

• Industrial machinery and structural health monitoring

The optional weather-resistant housing allows reliable outdoor operation, even in harsh environmental conditions.
