JQX-2 Digital Portable Inclinometer

2022-11-18

Introduction

The top Angle and azimuth Angle of drilling holes, foundations, walls, and dam slope engineering constructions are measured using an inclinometer.

The inclinometer is a type of in-situ monitoring device used to gauge the borehole's azimuth and inclination. An inclinometer was employed in the 1950s of the previous century to track in-situ geotechnical engineering projects like earth-rock dams, roadbeds, slopes, and tunnels.
In the domains of water conservation and hydropower, mineral metallurgy, transportation, and urban development geotechnical engineering, a variety of inclinometers are frequently employed, and they play a significant role in assuring the safety of geotechnical engineering design, construction, and use.

Fundamental Theory of Operations

(Cautions: these sensors inside the probe are accurate devices, which are forbidden to crash down and
destroy or else you will take accountable for them.)
Interior of the probe these are two linear inclination sensors, by whose output signals you can count out the vertex angle.
Measurement of magnetic field consists of three sensors that are perpendicular to each other. Each sensor direction will record
its corresponding magnetic strengthens and its sensibility is match with the dimension of this direction. Influence in the axis
direction, where the sensor can tell from each other in a resolution of 1mG, is little. So two dimensions determine the azimuth.
