Installation Steps:
- Choose a Mounting Location: Select a stable, flat surface on the equipment (e.g., motor, water pump casing) where vibration is to be monitored. Ensure the surface is clean and free of debris.
- Secure the Sensor:
- Magnetic Mounting: If using the magnetic base, simply place the sensor firmly onto the chosen metallic surface. The strong magnetic force will hold it in place.
- Threaded Mounting: If a permanent or more secure installation is required, use the M8*1.25mm threaded hole on the sensor base to bolt it to the equipment.
- Orientation: For accurate three-axis measurements, ensure the sensor is oriented consistently with the X, Y, and Z axes of the equipment being monitored. The sensor is designed to simultaneously measure vibration speed, amplitude, displacement, and frequency along these three axes.

4. Operating Instructions
The WT-VB02-485 sensor is designed for continuous vibration monitoring. Once installed and powered, it begins collecting data.
4.1 Data Output
The sensor outputs comprehensive data including three-axis vibration (speed, acceleration, angular velocity, angle, displacement, frequency), chip temperature, and on-chip time. This data is transmitted via TTL serial communication.
4.2 Modbus Protocol Support
The sensor supports the Modbus protocol, allowing for easy integration with various industrial control systems and host computers. By connecting the sensor to a PC host computer, users can view real-time sensor status and collected data.
For systems requiring multiple sensors, up to 128 units can be cascaded for simultaneous attitude measurement. For detailed cascading instructions and recommendations, please contact customer service.
4.3 Environmental Considerations
The sensor features an IP67 waterproof and dustproof rating, making it suitable for harsh environments. It can withstand daily splashes or rainy weather and can be submerged in water for up to 30 minutes without affecting operation. The operating temperature range is -40°C to +85°C.
5. Maintenance
The WT-VB02-485 sensor is designed for low maintenance. Follow these guidelines to ensure optimal performance and longevity:
- Regular Cleaning: Periodically clean the sensor's exterior with a soft, damp cloth to remove dust and debris. Avoid using harsh chemicals or abrasive materials.
- Inspect Connections: Regularly check all wiring connections for tightness and signs of wear or corrosion. Ensure cables are not pinched or damaged.
- Environmental Protection: While the sensor is IP67 rated, prolonged exposure to extreme conditions beyond its specified limits should be avoided.
- Firmware Updates: Check the manufacturer's website periodically for any available firmware updates that may improve performance or add new features.
6. Troubleshooting
If you encounter issues with your WT-VB02-485 sensor, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
