Working Principle

The core component of the slope inclinometer is the tilt sensor. Common tilt sensors include accelerometer type and electrolyte type. Taking the accelerometer type as an example, it is based on Newton's second law, that is, an object will generate force under the action of acceleration. When the inclinometer tilts, the mass block inside the accelerometer will generate an acceleration signal related to the tilt angle due to the component of gravity. This signal can be converted into an electrical signal through the circuit inside the sensor.
For the electrolyte tilt sensor, it uses the fluidity of the electrolyte. When the instrument tilts, the electrolyte will flow under the action of gravity, thereby changing the electrical properties such as capacitance or resistance between the electrodes inside the sensor, and then generating an electrical signal corresponding to the tilt angle.

Our Advantages

High-precision measurement
It can accurately measure small changes in tilt angles, and the general accuracy can reach ±0.01° - ±0.1°, which is very critical for monitoring small displacement changes of slopes. Through high-precision tilt angle measurement, the horizontal displacement calculated by mathematical methods such as trigonometric functions is also highly accurate, which can accurately reflect the displacement state of different depths inside the slope and provide reliable data support for slope stability assessment.
Real-time monitoring capability
Many modern slope inclinometers have real-time monitoring functions. It can be installed on the slope site, and the measurement data can be sent to the computer system of the monitoring center in real time through wired or wireless data transmission to obtain dynamic change information of the slope in a timely manner.
Adapt to various environmental conditions
It can adapt to different climatic conditions, whether it is high temperature, severe cold, or humid and dry environment, it can work normally. The shell of the instrument is made of stainless steel to ensure long-term stable operation in an open-air slope environment. In addition, for different types of geological conditions, such as slopes composed of soft soil, rock, sand, etc., the inclinometer can effectively measure, and can select suitable inclinometer tubes for burial according to specific geological conditions and engineering requirements.
Non-destructive measurement
It uses the method of burying inclinometer tubes inside the slope for measurement, which belongs to non-destructive monitoring methods. Compared with some traditional exploration methods, it will not cause greater damage to the soil or rock structure of the slope. After the inclinometer tube is buried, in addition to providing a measurement channel for the inclinometer, it has little effect on the stability of the slope itself, and during the entire monitoring period, it can continuously and stably obtain the displacement change data inside the slope, which is conducive to long-term and dynamic observation of the evolution of the slope.
Acquisition of detailed information in the depth direction
The slope inclinometer can measure at different depths along the inclinometer tube, and can provide detailed distribution of the displacement inside the slope in the depth direction.
High degree of automation
The time interval for automatic measurement can be set, such as every few minutes, hours or several times a day. It can automatically complete a series of operations such as data collection, storage and transmission, reducing the need for manual intervention and improving monitoring efficiency. At the same time, the supporting software system can also automatically process and analyze the collected data, such as drawing displacement-time curves and generating reports.
Good long-term stability
Since slope stability monitoring is usually a long-term process, the slope inclinometer shows good stability during long-term use. The key components of the instrument, such as sensors and data acquisition systems, have been carefully designed and rigorously tested to maintain stable performance over a long period of time. Its internal calibration mechanism can automatically correct measurement errors to a certain extent, ensuring that accurate and reliable measurement data can be continuously provided during monitoring cycles of months or even years.
