Array Displacement Meter

The Beijing Chengan CA-ZL03 array displacement meter is a flexible, standardised 3D measurement system. It uses a dense array of micro-electro-mechanical-system accelerometers together with a proven calculation program to measure 2D and 3D deformation. There is no preferential axis, it can be bent freely, and there are various installation methods: it can be installed vertically, horizontally or in a ring. The array displacement meter measures the change in acceleration of the accelerometers along different axes to reflect the corresponding change in the angle between each axis and the direction of gravity, and from the change in angle it then derives the change in displacement of the corresponding node. The array displacement meter uses advanced measurement and control technology, gravitational acceleration measurement technology, sensor temperature compensation technology and core algorithm technology to achieve real-time monitoring of the X, Y and Z three-dimensional deformation of a monitored object.

Key Features

(1) Fully automatic: real-time, continuous and highly reliable.
(2) Ease of use: simple installation and long-term maintenance-free operation.
(3) Good performance: high accuracy, good stability and a large range.
(4) Full functionality: the X, Y and Z three-dimensional displacement of a measuring point can be obtained simultaneously.
(5) Wide range of uses: suitable for all kinds of deformation monitoring, can be installed at any angle and can also measure vibration.
(6) Strong adaptability: adapts to long-term operation in various harsh indoor and outdoor environments.
(7) Reusable: it can be repeatedly assembled and used according to engineering needs, reducing use costs.
1.2 Product use
The array displacement meter is widely used for three-dimensional real-time monitoring in geotechnical engineering, reservoir dams, building excavations and mine slopes. By measuring, through a built-in MEMS micro-electro-mechanical system, the change in acceleration along different axes, it achieves continuous dynamic measurement of a monitored object in the X, Y and Z three-dimensional directions. Combined with the core algorithm of the Beijing Chengan monitoring cloud platform, it produces high-precision, stable and reliable monitoring results. It is widely used for deep displacement monitoring in geotechnical engineering, convergence monitoring and settlement monitoring of highway and railway tunnels, settlement monitoring of highway and railway subgrades, deep displacement monitoring of reservoir dams, deep displacement monitoring of building excavations, and deep displacement monitoring of slope and landslide bodies.
