Audited Supplier This test method can replace sand filling method and water filling method, the test speed is fast, the precision is high, the operation is simple.
Application Summary:
Air bag volume measuring instrument is a test instrument for measuring the density of soil, which is suitable for field measurement. The density of soils with large particle sizes less than 20mm.
Applicable standard: Code for Geotechnical Test of Railway Engineering (TB 10102-2004).
Working principle:
The balloon volume meter is based on Boyle's law of physics; During the test, a certain pressure is used to push the piston to transfer the medium (air) in the cylinder to the air bag placed in the test pit, so that the air bag expands 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.
| Cylinder volume | 5200cm3 |
| Piston stroke | 280mm |
| Air bag pressure | 8KPa |
| Digital display depth ruler resolution | 0.01mm |
| Volume constant piston area ×0.1cm3/mm | |
| Detection error | ≤ 1% |
| Test pit size | Φ150mm×200mm |
| Handle operating force | ≤200N |
| The machine weight | 5.2kg |
| Dimension | Φ255mm×627mm |
| Instrument composition | air bag type volume measuring instrument is mainly composed of air bag, cylinder, piston, pressure mark, digital depth ruler, pit ring, pedal. |
