Hydraulic static level settlement monitoring instrument

Description :

　　1: Monitoring purpose and basis

　　Deformation monitoring is the use of measuring instruments and other specialized instruments and methods to monitor, observe, and ultimately determine the shape, size, spatial state, and temporal characteristics of deformation under various loads and external forces. Therefore, the purpose of deformation monitoring can be described as follows:

　　1) Deformation monitoring is a safe means of engineering management and operation.

　　2) By observing, analyzing, and studying deformation bodies during construction and operation, the calculation methods of foundations and engineering structures can be verified, and reasonable allowable settlement and deformation values can be specified for different foundations and engineering structures. This provides relevant information for the design, construction, maintenance management, and scientific research of engineering buildings, and analytical data for the safety evaluation of building structures.

　　3) By comparing monitoring data with predicted values, it is possible to determine whether the previous construction process and parameters meet the expected requirements, in order to determine and optimize the next construction parameters, achieving dynamic design and information-based construction.

　　4) By comparing monitoring data with predicted values, it is possible to determine whether the previous construction process and parameters meet expectations, in order to determine and optimize the next construction parameters, achieving dynamic design and information-based construction.

　　5) Deformation monitoring is a necessary means for people to obtain scientific knowledge, test theories and hypotheses through deformation phenomena. By collecting monitoring data, accumulate experience for the development of similar engineering design, construction, and related regulations.

　　Based on the on-site investigation results and our company's years of experience in building monitoring, taking into account the site conditions and equipment installation requirements, this monitoring provides a clear, concise, and user-friendly Chinese operating interface for the management platform. Easy to operate, flexible and easy to maintain.

　　Legitimacy: The scheme design complies with relevant national and industry regulations, as well as technical prevention requirements.

　　Practicality: Adopt economically practical technologies and equipment, comprehensively consider the construction, upgrade, and maintenance costs of the system, and do not blindly invest; The scheme design meets the system requirements, fully considers the usage requirements of various units and customers, maximizes the functionality of the equipment, and fully utilizes it to ensure stable, efficient, and long-term operation of the equipment; Ensure timely after-sales service.

　　Reliability: The system design, equipment selection, debugging, installation and other aspects will strictly implement quality regulations, fully comply with the bidding documents, relevant national and industry standards, and safety technical prevention requirements of relevant departments. The system has consistency, upgrade capability, and technical support, which can ensure long-term stable operation 24/7.

　　Progressiveness: In the system design, we fully consider the development of technology in the field of tunnel monitoring, refer to the current development level of railway tunnel monitoring equipment, select qualified and stable products on the equipment, and ensure that our monitoring technology is in the domestic position.

　　The HR8066 high-precision static level is suitable for monitoring vertical displacement or settlement with high requirements, and can monitor liquid level changes up to 0.01mm. The instrument consists of a series of containers containing liquid level sensors, which are connected by liquid filled connecting pipes between multiple containers. The reference container is located at a stable reference point, and any elevation change between the container and the reference container will cause a corresponding change in the liquid level inside the container. The elevation change of the measuring point can be obtained by measuring the liquid level change.

　　The instrument has RS485 digital signal, which facilitates data acquisition. High measurement accuracy, no drift, strong reliability, and easy installation. The sealed shell has good moisture resistance and can work continuously for a long time in a relative humidity environment.
