BKN-A
Networked Inclination Transducer

Summary

Digital signal transmission realizes cable saving, high accuracy and high stability
Networked inclination transducers are designed for real-time measurement of lateral displacement of the ground affected by excavation or landslide of dangerous slopes.

Features

●Cascading multiple units with one cable between each unit
A maximum 50 units can be installed in the dedicated aluminum guide pipe with one cable between each unit without widening installation intervals even for extra deep sites, thereby improving measurement accuracy.
●Highly stable measurement with high resolution
Each inclination transducer digitizes detected signals and then transfers the digital signals to the junction box, thereby enabling highly stable measurement with high resolution and with least effects of noise and voltage decrease.
●One system can have up to 50 units installed, thereby enabling measurement at up to 500 points.
●Measurement software BKN-190A installed to a PC enables setting and controlling the cascaded inclination transducers as well as data acquisition.
●Maximum allowable distance is 900 m between the boring and PC.
●Maximum depth of the boring is 100 m.
