HYDRAULIC ANCHOR LOAD CELL HLC-6000

In stock

The Geosense® HLC-6000 series Hydraulic Anchor Load Cells consist of a sensitive pressure pad formed by joining two stiff steel discs at their periphery. The void inside the cell is filled with de-aired fluid. When load is applied to the cell the pressure of the inside liquid changes. The changes in pressure correspond directly to the load applied. Manufactured with a center hole to accommodate anchors, rock bolts and tendons.

VW HYDROSTATIC PROFILER

In stock

The Vibrating Wire Hydrostatic Profiler is used for the measurement of subsurface settlement. The sensor measures the hydrostatic head of liquid between the sensor and the reservoir locations.

BOREHOLE ROD EXTENSOMETER

In stock

The Geosense® GEO-XB2 borehole rod type extensometer range is used to measure and locate settlement, displacement and deformation in soil and rock. It consists of a reference head and one or more in-hole anchors each of which is placed at a known depth and connected to the reference head by either a rigid or flexible rod running inside a flexible sleeve, which keeps the rod de-bonded from the grout.

MULTI-POINT VW PIEZOMETER

In stock

Fully grouted installation permits multiple piezometers to be simply and reliably installed in a single borehole. The piezometer string and grout pipe are placed in the borehole and cement-bentonite grout is pumped until the borehole is filled.

STRAIN GAUGE ANCHOR LOAD CELLS SGLC-7000

In stock

The SGLC 7000 series load cell consists of a cylinder of high strength steel with a series of electrical resistance strain gauges connected around the periphery as a Wheatstone Bridge that compensates for unevenly distributed loads and provides a single mV/V signal output. They are manufactured with a center hole to accommodate anchors, rock bolts and tendons.

VW LOAD CELL VWLC-5050

In stock

The VWLC 5050 series of Vibrating Wire Load Cells consist of a solid cylinder of high strength steel with 3 vibrating wire strain sensors mounted parallel to the longitudinal axis arranged equidistant around the circumference which measure the compression of the cylinder under load.

PUSH-IN PRESSURE CELL

In stock

A Push-in Pressure Cell, also called Spade Cell, is designed to be pushed into the ground where it can measure total earth pressure and pore water pressure within the soil. It can be used as a site investigation tool to determine the in-situ stress state, both vertical and horizontal, depending on the direction of installation. In addition, it can be used to monitor the change in active and passive pressure around retaining structures (diaphragm walls etc) as well as in tunnelling, and other earthworks. Typical installations are in fine grained cohesive soils, including very soft to stiff clays.

LOAD CELL FOR TUNNEL LININGS AND STRUTS

In stock

This type of load cell is used to monitor stresses in steel linings, struts, piles and support beams. It consists of a sensitive pressure pad formed by joining two stiff steel discs at their periphery. The void inside the cell is filled with de-aired fluid. When load is applied to the cell the pressure of the inside liquid changes. The changes in pressure correspond directly to the load applied. The pressure in the loads cell is measured by a resistance transducer.

STRAIN GAUGE LOAD CELL SGLC-7050

In stock

The SGLC 7050 series load cell consists of a solid cylinder of high strength stainless steel with a series of electrical resistance strain gauges connected around the periphery as a Wheatstone Bridge that compensates for unevenly distributed loads and provides a single mV/V signal output.
