Sliding Inclinometer: Reliable Subsurface Monitoring
Sliding Inclinometer
When there is slight displacement in the slope or foundation pit, it often means that potential risks are accumulating. In order to capture this kind of displacement change of deep soil, the sliding inclinometer is one of the most commonly used tools by geotechnical engineers around the world. Kingmach's sliding inclinometer system can continuously measure the horizontal displacement along the depth direction inside a borehole or structure through a set of probes and matching inclinometer tubes. Compared with single-point measurement, this system can be used repeatedly, is cost-effective, and is suitable for long-term monitoring. We provide configurations with different ranges and accuracy according to the actual needs of the project, and support customized inclinometer solutions. From tunnel excavation to dam safety, Kingmach's sliding inclinometers are already in use in dozens of countries. The following is a detailed introduction to the core features of this system and aspects that need attention in actual use.
Technical Detail
Configured around process stability, mold life, and long-term uptime.
Kingmach's sliding inclinometer probe has a built-in high-sensitivity sensor, usually using MEMS or servo accelerometer technology, with a resolution of 0.01mm/500mm. This accuracy is sufficient to detect small deformations of the soil in its early stages. The probe shell is sealed and pressure-resistant and can adapt to the harsh environment of deep holes. The accompanying data collector supports Bluetooth transmission, which can send real-time data to the mobile app, and the displacement curve can be viewed on site. The standard inclinometer tube of the system is made of aluminum alloy and ABS plastic. Customers can choose according to the hole depth and budget. For special projects, we offer custom lengths of cable and probes in different wheel sizes to accommodate a variety of inclinometer inside diameters. Kingmach has distribution networks in many countries around the world and can quickly respond to technical support and after-sales needs. Whether it is routine slope monitoring or complex subway foundation pit engineering, our sliding inclinometers have accumulated a lot of application experience. In actual use, the focus of maintenance is to regularly check the probe zero drift and cable wear. These are detailed instructions in our operation manual.

FAQ
Common technical questions
What is the measurement principle of the sliding inclinometer?
The probe slides along the guide groove in the inclinometer tube, and the inclination angle change is measured at a certain depth at intervals, and the cumulative horizontal displacement is calculated through integration. Biaxial sensors are usually used to monitor displacement in two orthogonal directions at the same time.
What are the key points to pay attention to when installing the inclinometer tube?
The inclinometer pipes need to be buried vertically as much as possible. When connecting pipe sections, they should be aligned with the guide grooves and fixed. The backfill material should be dense and without gaps. The bottom of the pipe should be fixed to avoid the influence of buoyancy. After installation, the initial value should be read as a benchmark.
What data collection methods does Kingmach's sliding inclinometer support?
It can be used with a handheld reader to record data manually; it also supports an automatic data acquisition system, which can be transmitted to a remote server via cable or wireless means to achieve real-time monitoring and early warning.
How to ensure the accuracy of long-term monitoring?
Regularly check the zero point of the probe on a calibration table with known verticality to check the data drift trend. Keep the cable joints clean and dry, and replace worn seals in a timely manner. If the inclinometer tube is excessively twisted or blocked, it needs to be reinstalled.
Can you customize the inclinometer system according to project requirements?
Yes. We provide probes with different ranges and wheelbases, as well as cables and pipes of special lengths. According to on-site conditions, the data collection frequency and alarm threshold can also be customized to meet various engineering monitoring requirements.
