BeanDevice 2.4 GHz AX-3D
Available in two versions (measurement range: ±2g or ±10g), the BeanDevice® 2.4GHz AX-3D is a wireless vibration sensor with built-in data logger. While the vast majority of wireless sensors are not suitable for harsh industrial environment, the BeanDevice® 2.4GHz AX-3D integrates an innovative antenna diversity design, boosting the radio link quality in environments subject to random and diverse disturbances.
