Accuracy: 0.1mm

Model: SDD-225


Application principle:
In use, the liquid level chambers of multiple static level gauges are connected in series to the liquid level container through liquid pipes, measured by high-precision capacitive sensors, and transmitted to the signal acquisition system through RS485 signals. By monitoring the changes in liquid level, the signals are transmitted to the signal acquisition system. Through analysis and calculation, they change with the changes in liquid level measurement, and the relative settlement height of the ground surface is analyzed by measuring the liquid level changes at each measuring point.

Product Description:
The SDD-225 capacitive level is composed of a liquid reservoir, a capacitive probe, a specially customized circuit module, a protective cover, and other components. Suitable for high-precision liquid level measurement in small ranges. Mainly used for measuring the settlement of subway tunnels, building foundations, and dams.


Product Usage:
Static level is a high-precision liquid level measuring instrument used to measure the relative settlement of various measuring points in foundations and buildings. Application sites include large buildings such as hydroelectric power plants, dams, high-rise buildings, nuclear power plants, water conservancy hub projects, and the measurement of uneven settlement at various measuring points such as railways, subways, and high-speed railways
