LQ-080U Soil Stress Gage

The LQ-080U Series of soil stress gages is designed to meet the requirements of weapons test labs civil engineering field to make accurate measurements of blast induced soil reactions. Insertion of a gage in soil disrupts the stress field and induces either stress concentrations or reliefs depending on gage thickness. This stress-transfer phenomenon can seriously affect gage accuracy. To overcome this problem, the LQ-080U employs a pair of extremely stiff diaphragms with a diameter-to-thickness ratio of greater than 5 and a diameter-to-deflection ratio of greater than 2000. This design together with good gage-medium matching ensures accuracy and repeatability of readings. The DC energized sensing element of the LQ-080U comprises 4-active semiconductor strain gages directly bonded to the measuring diaphragms. The output may be conveniently monitored on most conventional instrument systems. During assembly, the entire unit is given a conformal coating to prevent any ingress of moisture after final on-site-installation. The LQ-080U Series is available calibrated or uncalibrated, with or without mounting ring. No mounting ring available for 10K PSI.
