- Scalable Measuring Range ±1.2g and ±2.4g -
BeanDevice® 2.4GHz AX-3D-SR

The BeanDevice® 2.4GHz AX-3D SR is a cutting-edge wireless vibration sensor offering a scalable measuring range (±1.2G and ±2.4G, with automatic range adjustment based on your application’s requirements). This high-performance device delivers exceptional accuracy (±1 mg for ±1.2G and ±2 mg for ±2.4G at 1 Hz) and features an integrated temperature sensor (located on the device base) to monitor the temperature of your equipment or structures.
This IoT sensor is available with flexible configuration options:
• Mounting: Choose between screw-based or magnetic mounting options.
• Antenna: Select a High-Gain Antenna for extended wireless range or a Radome Antenna for space-constrained applications.
Additionally, it comes with the eco-friendly BeanScape® 2.4GHz Lite supervision software (at no additional cost), which allows users to display real-time data and back up measurements to CSV log files.
