BKL-A
Guide Roller-equipped Inclination Transducer

Summary

Inclination angles detected enable measurement of lateral displacement of the ground or earth retaining wall.
The BKL-A series inclination transducers are designed for embedment at multiple stages in the ground or earth retaining wall. Inclination angles detected at multiple stages enable measurement of lateral displacement of the ground or earth retaining wall. Guide rollers provided ensure smooth installation in an aluminum guide pipe embedded beforehand, and no grouting work in the guide pipe is required.

Features

●Guide rollers ensure smooth installation.
●No grouting work required in the guide pipe
●Installable at maximum 15 stages

To Ensure Safe Usage

To protect the cable, it is recommended to connect the dedicated aluminum guide pipe using an adhesive or screws (M4x4). Do not use rivets.

Remarks

Different from KYOWA insertion type inclination transducer BK-G, the BKJ-A cannot be lifted up and down for measurement.
