Flexible Inclinometer (Array Displacement Sensor) Product Introduction
The Cyber-Terra Measurement and Control AFIC series array displacement sensor is a flexible and versatile 3D measurement system. It uses a dense array of MEMS (Micro-Electro-Mechanical Systems) and validated model calculation programs to measure 2D and 3D deformations. The AFIC series array displacement sensor has no preferred axis and can be bent freely. It can be installed vertically, horizontally, or in a ring configuration.
The Cyber-Terra Measurement and Control AFIC series array displacement sensor reflects the angular changes in the corresponding axis and gravity direction by measuring the acceleration changes in different axial directions and calculates the corresponding node's displacement changes based on the angle changes.
The Cyber-Terra Measurement and Control AFIC series array displacement sensor utilizes advanced measurement and control technology, including gravity acceleration measurement, sensor temperature compensation, core algorithm modeling, etc., to achieve real-time online monitoring of X, Y, and Z three-dimensional deformations of the monitored object.
Structure of the Flexible Inclinometer(Array Displacement Sensor)
The flexible inclinometer, also known as an array displacement sensor, consists of a fixed-length steel pipe and a flexible joint at each node. Each steel pipe contains an independent intelligent MEMS (Micro-Electro-Mechanical System) device.
MEMS (Micro-Electro-Mechanical System) is a high-tech device composed of sensors, actuators, and micro-power sources.

Temperature Compensation/Data Stability
The AFIC series flexible inclinometer utilizes MEMS (Micro-Electro-Mechanical Systems) technology and achieves highly integrated design, effectively eliminating errors between axes. The temperature compensation model is employed in the range of -40°C to +60°C to eliminate temperature drift, ensuring the stability of AFIC data acquisition. In experimental environments, this series of products exhibits optimal data fluctuation of only 0.01mm.
Accurate Direction/Reliable Accuracy
Before leaving the factory, each node of the AFIC series flexible inclinometer undergoes independent calibration using a high-precision automatic calibration system. After assembly, a comprehensive calibration is performed again to ensure the accuracy in the X, Y, and Z directions. The displacement resolution of the inclinometer is up to 0.005mm within a measurement range of 500mm.
Offset Correction/Torsion Correction
During the initial installation of the flexible inclinometer, if the inclinometer casing has undergone torsion, it can be corrected based on the angle between the initial Mark line direction of the flexible inclinometer during installation and the direction of the deformation to be measured. This ensures the accuracy of the monitoring direction.
After the installation of the flexible inclinometer is completed, during the monitoring process, if the inclinometer casing undergoes torsion, the angles generated by the twisting of the flexible inclinometer during the casing's torsion process can be corrected to ensure the accuracy of the measurement results
Online Transmission/Real-time Analysis
The AFIC series flexible inclinometer supports multiple communication methods such as 4G network and serial port. After installation, simply power it on and perform basic settings, and the monitoring data can be collected and transmitted online in real-time. The maximum sampling frequency can reach 1 time per second. Users can perform real-time analysis and download data through the monitoring cloud platform.
Secondary Development/Platform Compatibility
The AFIC series flexible inclinometer has an open protocol and strong compatibility. Users can connect the array displacement sensors to data loggers of other brands for data transmission according to their needs. They can also feed the monitoring data from the array displacement sensors back to other monitoring software for viewing.
Modular Design/Reusable
The AFIC series flexible inclinometer adopts a modular assembly design, allowing users to combine and freely assemble the array displacement sensors on-site according to different monitoring project requirements. This enables true reusability of the inclinometer, as the total length of the array displacement sensors can be customized and adjusted as needed.
