Manufacturer: Kyowa Electronic Instruments Co., Ltd.
Model: BKN-A-10-1

Digital transmission realizes reduced wiring, high accuracy and high stability This system can perform real-time measurement of lateral displacement of the ground due to excavation of the ground in civil engineering work and landslides on dangerous slopes.

Features

●One Cable Network
By connecting adjacent inclinometers with one cable, it is possible to install up to 50 stages on an aluminum guide pipe, improving measurement accuracy even at great depths without increasing the installation interval

●High resolution, high Stable
Measurement Because the inclinometer performs AD conversion and transmits digital signals, it is less affected by noise and voltage drops, and enables high-resolution, highly stable measurements.Installation of up to 50 network inclinometers per system; Capable of measuring up to 500 points
●Settings, control, data acquisition, etc. are performed using measurement software on a single computer (*1)
●The distance from where the computer is installed to the hall can be up to 900 meters
●Hall maximum depth of 100m
