BKJ-A
Small-sized and lightweight 27 mm in outer diameter. Inclination angles detected at multiple stages enable measurement of lateral displacement of the ground or earth retaining wall.
The BKJ-A series inclination transducers are designed for embedment at multiple stages in a boring or earth retaining wall. Inclination angles detected at mutiple stages enable measurement of lateral displacement of the ground or earth retaining wall. Since the embedment method ensures quicker measurement than the insertion method, the BKJ-A series is suitable for use in information-oriented urban civil engineering fields. The BKJ-A series can be installed at maximum 20 stages in an aluminum guide pipe embedded beforehand
?? Facilitate quicker and easy data recording since the BKJ-A series is installed in an aluminum guide pipe
?? embedded beforehand in a boring or earth retaining wall.
?? Allows installation at maximum 20 stages in a guide pipe.
?? Available in uniaxial and biaxial types for selection to meet individual applications
?? Designed for high immunity against lightning surge
