Biaxial Stressmeters-Model 4350
<p>The Model 4350 Vibrating Wire Biaxial Stressmeter is designed to measure compressive stress changes in rock, salt, concrete or ice. Three or six Vibrating Wire sensors oriented at 60° intervals allow the principal stress changes to be measured in the plane ...
Borehole Pressure Cells
<p>Borehole Pressure Cells have a long term track record of stress monitoring in both elastic and viscoelastic rock</p>
Borehole Pressure Cells-Model 3200
<p>The standard Borehole Pressure Cell (BPC) is used to measure rock stress changes and is designed to be grouted inside a borehole. The BPC is manufactured from two steel plates welded together around their periphery. The plates are deformed into a “dog bone” ...
Earth pressure cells L141 & L143
<p>Earth pressure cells (or total pressure cells) are used to monitor total pressure in earthfill dams and embankments or placed at the interface between the structure and the wall of excavation.<br><br>Earth pressure cells are constructed from two stainless ...
NATM Style Shotcrete Stress-Model 4850
<p>The Model 4850 NATM Style Shotcrete Stress Cells are designed for the measurement of tangential (4850-1) and radial (4850-2) stresses in shotcrete tunnel linings. The cells consist of two rectangular steel plates welded together around the periphery with ...
Rebar Strainmeters (Electrical Resistance) - Model 3911/3911A
<p>Model 3911 Electrical Resistance Type Rebar Strainmeters are designed primarily for monitoring the stresses in reinforcing steel in concrete structures, such as bridges, concrete piles and diaphragm walls. They are particularly suitable where dynamic strain ...
Soft Inclusion Stress Cells-Model 4360
<p>The Model 4360 Vibrating Wire Soft Inclusion Stress Cells (SISC) are larger versions of the Model 4300 Borehole Stressmeters. The SISC is pre-loaded by wedging it into a large size diamond drill hole using an integral screw mechanism or hydraulic piston ...
TPC Total Pressure Cell
<p>The TPC cells consist of a sealed distribution pad, composed of two plates welded together around the periphery and filled with de-aired oil. The pad is connected via a length of steel tube to a pressure transducer. Variation in oil pressure resulting from ...
