Introduction: DM-JL01 hydraulic static level is a special precision instrument for measuring the relative elevation change between the measuring points of the foundation and buildings. It is widely used in precision measurement of settlement or buoyancy of basic filling structures such as housing construction, deep foundation pits, highways, bridges, embankments, oil and gas pipelines, oil storage tanks, subways, etc. Based on the principle of the connector, the system fills the nylon connecting tube with specially prepared SG liquid, and connects the connecting tube to the measuring point containers installed at each design position and elevation, and at the same time installs the reference (datum) container on a stable leveling base point. and connect the connecting pipe. The system does not have strict requirements on the buried elevation of the container at each measuring point, and only needs to bury and install the container of each measuring point according to the design requirements. The measuring point container is composed of upper and lower end caps and a plexiglass cover, and a hydraulic sensor is installed inside. When the measuring point changes relative to the reference container and the reference sensor or between any measuring point, the level of the whole system will change. The output readings can be collected online by the DM-CJ acquisition instrument, and then the relative subsidence between each point and the base point can be obtained by calculation. Each set of static level is composed of hydraulic gauge, liquid storage tank, antifreeze, pressure-inducing liquid communication pipe, ventilation pipe, observation cable and installation bracket. Multiple static levels plus the reference water level point, together with the acquisition system, can form a complete set of static level settlement monitoring system. Features 1. Hydraulic sensing principle, 485 serial port signal output; 2. High measurement accuracy, long-term stable performance, sturdy and reliable; long service life. 3. Large measuring range and high sensitivity. 4. Waterproof, corrosion-resistant, long-term reliability, suitable for telemetry and automated data acquisition 5. The installation is convenient, and there are no strict requirements on the elevation between different installation points. Technical parameter: Product Name: Static Level Range: 0.2-500mm Resolution ("): 2 Resolution: 0.001mm Accuracy: 0.1%FS Communication method: RS485 (Zigbee, Wifi) External power supply: DC 5V Temperature range: -30~80 degrees Protection class: IP67 General selection protocol: Serial port protocol (protocol can be provided externally, supporting secondary development) Accessories: cable, catheter, protective tube, reference tank, SG solution
