NR-150 air bag type soil density meter
Usage overview
The NR-150 air bag type soil density meter is a test instrument for
measuring the density of soil, and is suitable for on-site
measurement of the density of soil having a maximum particle
diameter of less than 200 mm.
Applicable standard
"Code for Geotechnical Testing of Railway Engineering"
(TB10102-2010)
working principle
The NR-150 air bag type soil density meter designed according to
the physics Boyie law; during the test, the piston is used to push
the medium (air) in the cylinder to the air bag placed in the test
pit with a certain pressure to expand the air bag. Close to the
inner wall of the test pit; record the data displayed by the
measuring device and calculate the volume of the test pit.
