GN-1B Smart Fixed Inclinometer with MEMS Sensor and RS485 Output for Deformation Monitoring
GN-1B Smart Fixed Inclinometer is designed for measuring horizontal displacement, vertical settlement and landslide deformation of engineering structures such as earth-rock dams, concrete face dams, geotechnical slopes, embankments and foundation pits. Used together with an inclinometer casing, the sensor can be repeatedly measured and is suitable for automatic data acquisition in long-term monitoring projects. The fixed inclinometer uses a high-precision MEMS sensor with reliable performance, fast stabilization and stable measurement values. It outputs RS485 digital signals and can directly provide engineering values such as displacement or angle. The embedded point temperature can also be measured synchronously.
