Product Overview:
The Wireless Bolt Loosening Detection Sensor is a high-precision industrial-grade monitoring device designed to detect the loosening status of critical bolts in real-time. Utilizing advanced MEMS technology, this non-intrusive sensor measures the relative rotation angle between the nut and the bolt to determine fastening integrity. With wireless communication capabilities and a robust, low-power design, it is ideal for deployment in demanding industrial environments.
Key Features:
- Non-Intrusive: No need to modify bolt structure; maintains original mechanical strength.
- High Accuracy: Angular measurement precision within ±0.5°, resolution 0.01°.
- Wireless Transmission: 2.4GHz ISM band with Bluetooth 5.0 support; up to 300m line-of-sight.
- Ultra-Low Power: Built-in 1200mAh replaceable battery; over 10 years of service life.
- Durability: IP67 protection; resistant to water, dust, corrosion, and vibration.
- Remote Monitoring: Real-time alerts, data visualization, and diagnostics via cloud or app.
