Pipe inclinometer Dr.Clip.

Boring is performed on sloping surfaces, etc., and multiple inclination sensors are buried to monitor changes in inclination. It is useful for disaster prevention such as landslide, debris flow, crustal movement, and landslide. Continuous data acquisition is possible, and long-term observation enables monitoring of changes in groundwater flow during rainy seasons. Multi-point measurement of surface, middle, and deep layers is possible. Minimization of installation space, area, and borehole diameter is possible. Observations can be made on a yearly basis for long-term analysis and monitoring. This product was developed jointly with Meiji Consultant Co.

Features

01 Enables measurement of site inclination and groundwater level in a single borehole.

02 MEMS acceleration sensor is mounted on the pipe with a unique waterproof structure to achieve high durability

03 Space in the pipe allows the use of conventional water level sensors, etc.

04 Simple structure with a single sensor cable for easy wiring

Simple structure with a single sensor cable for easy wiring

Inclination sensors are connected in series every 1m

05 Tilt direction can be corrected by attaching an azimuth sensor

06 Long-term observation (up to one year) is possible, making it possible to obtain desired data during periods of heavy snowfall or snowmelt.

Supplementary explanation

The standard inclination sensor is equipped every 10 m, enabling calculation of the inclination direction at each depth.
