Arc Weldable Strain Gages<\/h2>\n

Geokon 4000 Vibrating Wire Strain Gage<\/strong> is designed primarily for arc welding to steel structures such as tunnel linings, excavation bracing, piles and bridges. The gage has a 150 mm gage length (longer or shorter versions are also available), a 3000 \u00b5\u03b5 range and a 1 \u00b5\u03b5 sensitivity. The gage can be adapted for bonding to concrete or for bolting to steel surfaces by modification of the end blocks.<\/p>\n

Concrete Embedment Strain Gages<\/h2>\n

Concrete Embedment Vibrating Wire Strain Gages<\/strong> are designed for direct embedment in concrete.<\/p>\n

Geokon 4200<\/strong> (standard model) has a 153 mm gage length and 1 \u03bc\u03b5 sensitivity and is commonly used for strain measurements in foundations, piles, bridges, dams, tunnel linings, etc.<\/p>\n

Geokon 4210<\/strong> has a 250 mm gage length making it particularly suitable for use in large aggregate concrete.<\/p>\n

Geokon 4202<\/strong> is designed for laboratory use and\/or where there are space limitations. Low modulus versions, for measuring concrete curing strains, are also available.<\/p>\n

Displacement Transducers<\/h2>\n

Geokon 4420 Crackmeter<\/strong> is intended to measure movement across surface cracks and joints. It is installed by grouting, bolting, or bonding two threaded anchors (with ball joints) on opposite sides of the crack and then attaching the ends of the gage to the anchors.<\/p>\n

Geokon 4425 Convergence Meter<\/strong> is used to monitor closures in underground excavations, tunnels, etc. It is comprised of a spring tensioned transducer, turnbuckle, connecting rod (stainless steel, fiberglass or graphite), rod clamp, and a pair of stainless steel eyebolts.<\/p>\n

Piezometers<\/h2>\n

Geokon 4500 Standard Piezometer<\/strong> is designed to measure fluid pressures such as ground water elevations and pore pressures when buried directly in embankments, fills, etc. Also for installation inside boreholes, observation wells and standard (>19 mm diameter) piezometer riser pipe.<\/p>\n

Geokon 4500SH<\/strong> is designed with a heavy duty housing for pressures that exceed 3 MPa.<\/p>\n

Geokon 4500AL<\/strong> is designed for low-pressure ranges. The vented version (ALV) provides automatic compensation for barometric pressure changes.<\/p>\n

Thermistors<\/strong> are included to measure temperatures.<\/p>\n

Pressure Cells<\/h2>\n

Geokon 4850 NATM Style Stress Cells<\/strong> 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 a de-aired fluid occupying the space between the plates. A short tube connects the cell to a vibrating wire pressure transducer. A prestressing tube is provided for expanding the cell after the concrete has cured. Cells of this type are also used for measurements of stress in mass concrete.<\/p>\n

Geokon 4800 Earth Pressure Cells<\/strong> are designed to measure total pressure in earth fills and embankments. All cells consist of two circular stainless steel plates welded together around their periphery and spaced apart by a narrow cavity filled with de-aired oil. Changing earth pressure squeezes the two plates together causing a corresponding increase of fluid pressure inside the cell. A vibrating wire pressure transducer converts this pressure into an electrical signal which is transmitted to the readout location.<\/p>\n

Inclinometers<\/h2>\n

Geokon GK-604D Digital Inclinometer System<\/strong> is delivered in its entirety and includes a Model 6100D Digital Inclinometer Probe, a reel-mounted cable and a Field PC. The Model 6100D contains electronics to convert the analog voltage into a digital signal, which is transmitted by the control cable to the cable reel containing the Interface, which communicates via Bluetooth\u00ae to the Model FPC-1 Field PC. A Digital Compass is built into the Inclinometer Probe to correct the inclinometer data sets for any twist (or spiraling) in the inclinometer casings. The spiral survey data is presented on (and stored in) the same FPC-1 Field PC used for taking inclinometer readings.<\/p>\n
