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.
