Settlement Sensor (VW) Model 4600(M)

Admin — Thu, 22 Jul 2021 23:08:16 +0000

The Model 4600 Settlement System is designed for the remote measurement of surface or subsurface settlement in fills, surcharges, dams, embankments, etc. A borehole is drilled which allows a pressure transducer to be anchored to solid ground below the area of settlement. A fluid filled tube extends upward connecting the transducer to a reservoir which is located in the moving strata or fill. The measurement of fluid pressure indicates the elevation difference between the sensor and the reservoir. This design eliminates the need for long liquid filled tubes.

The Model 4600M is a special version of the Model 4600 capable of measuring subsurface zone settlement (please contact GEOKON for details).

The Model 4900 Vibrating Wire Load Cell consists of a cylinder of high-strength steel with 3, 4 or 6 vibrating wire strain gages located around the circumference of the cell. Loads applied to the cell are measured by the vibrating wire strain gages. The effects of uneven and eccentric loading are minimized by averaging the output of all 3, 4 or 6 individual readings.

Specifications

Rated Capacities¹:100 to 10,000
kNOver Range: 150% F.S.
Resolution: 0.025% F.S.
Accuracy²: ±0.5% F.S.
Temperature Range: −20°C to +80°C
Internal Diameters¹: solid, 25, 50, 75, 100, 125, 150, 200, 250 mm

¹Other capacities and diameters available on request. Calibrations that exceed GEOKON’S NIST traceable capacity of approximately 10,675 kN are subcontracted to an accredited testing laboratory. ²Established under laboratory conditions. System accuracy depends on end loading conditions.

Digital Inclinometer Model GK-604D

Admin — Thu, 22 Jul 2021 22:57:55 +0000

The Model GK-604D Digital Inclinometer System 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 wirelessly with the Model FPC-2 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-2 Field PC used for taking inclinometer readings. An optional 12 volt electric cable reel system is available, which can provide substantial time savings when surveying deep inclinometer casings.

Specifications

Standard Range: ±30°
Resolution (Probe): 0.0013°
Resolution (System)¹: ±0.025 mm/500 mm (±0.0001 ft/2 ft)
Total System Accuracy²: ±3 mm/30 m (±0.125 in/100 ft)
Temperature Range: −30°C to +85°C
Length × Diameter³: 700 × 25 mm, 1200 × 25 mm or 32 × 1 in
Wheel Base: 0.5 m, 1 m or 2 ft
Casing Size I.D. 48 to 89 mm (2 to 3.5 in)
