发明名称 Set pressure sensing and verifying device
摘要 A device for detecting soil compaction density comprising at least one shell material forming an enclosure, a failure plane disposed within the shell material which causes the shell material to fail at a preset static or dynamic pressure, and a detector, such as an odoriferous chemical enclosed within the enclosure which is released upon failure of the shell material, thereby indicating that the preset static or dynamic pressure has been achieved.
