2-axis tilt sensor WDS826FL

RS-485RS-232Modbus

Product Introduction
The WDS826FL is a dynamic dual‑axis tilt sensor engineered for monitoring tower motion and low‑frequency vibrations of wind turbines. It features high low‑frequency sensitivity and stability across wide temperature ranges, enabling accurate capture of slowly varying tilt signals in long‑term field deployments. Factory calibration and long‑term stability verification are performed to ensure consistent performance under varying environmental conditions.

Technical specifications / Notes

• Resolution: smallest detectable change within the measurement range
• Accuracy: measured across multiple angle points within the range at room temperature
• Zero‑point temperature coefficient: change in zero reading relative to room temperature over the rated range
• Sensitivity temperature coefficient: change in full‑scale reading relative to room temperature, expressed in ppm/°C
