The Aurora 313MM2-R1 is a three-axis, small-size, mid-to-high frequency bandwidth RS485 wired smart vibration and temperature sensor designed specifically for confined installation spaces. It integrates a vibration accelerometer, a temperature sensing chip, a high-speed computing unit and an RS485 data transmission module in a body of only 21 x 21 x 11.5 mm. It extracts the health status features of mechanical equipment in real time, evaluates its health condition, and uploads the equipment health information to various data collection systems through RS485-to-wired or wireless gateways.
It is suitable for early-warning diagnosis and remaining useful life estimation of gear speed-up/reduction mechanisms in automation equipment such as wafer transfer robots, automated storage systems, handling robots and AGVs; of components in high-speed equipment such as vacuum pumps, water pumps, air compressors, blowers and exhaust fans; and of motor components. The 313MM2-R1 performs time-domain analysis, FFT spectrum analysis and order tracking on the vibration signal, and calculates the overall vibration energy as well as the vibration energy features of various damage modes (eccentricity, misalignment, looseness, bearing damage, gear meshing damage and poor fluid transmission efficiency). You can customize the acceptable energy level of each damage mode, and when the energy feature of a mode exceeds the set limit, the 313MM2-R1 automatically issues a warning or an alarm. With built-in software trigger, hardware trigger, time-domain signal cleaning and speed identification, it handles variable-speed equipment and stop-and-go equipment with ease. Analysis results are transmitted via the Modbus protocol to PLCs or RS485-to-wired or wireless gateways, then uploaded to in-plant EDC/SCADA systems or offsite cloud systems, so you can monitor equipment status remotely and schedule maintenance in advance.
The Aurora 313MM2-R1 comes with the built-in ISO-20816 health grading index, so it delivers diagnostic benefits from the first day of deployment without a long period of data collection and learning. After deployment, you can still use the Aurora data and device management software to set the sampling mode, time-domain signal cleaning mode, machine damage modes and warning/alarm thresholds.

Scenario
When you have the following analysis requirements, we suggest you adopt the 313MM2-R1 smart vibration sensor:
- Wanting to know the health status of the field equipment and whether there are assembly or parts damage problems in real time.
- Wanting to estimate the appropriate repair time for field equipment.
- The installation space is small or restricted and a compact sensor is needed.
- There are numerous machines and equipment on site, but the budget that can be invested in the monitoring system is limited.
- The vibration direction of machinery and equipment tends to concentrate on three axes.
- High-speed operation of machinery and equipment, or complicated mechanical structure, leading to high-frequency vibration damage features.
