SISTER BAR REBAR STRAIN METER VWS-4000

In stock

The VWS-4000 series vibrating wire Sister Bars and Rebar Strain Meters are designed to be embedded in concrete to measure strains due to imposed loads.

TOTAL EARTH PRESSURE CELLS

In stock

TPC-4000 series Total Earth Pressure cells are designed to measure total pressure (effective stress and pore water pressure) in soils and at the interface between structures and the wall of excavation. Models 4010 and 4020 are designed to measure soil pressures on structures. They are fitted with an extra thick back plate on one side which is placed against the structure so as to avoid any warping of the cell. The other side has a thin plate welded to the back plate which provides sensitive measurement of soil pressures.

NATM PRESSURE CELLS NPC-3000

In stock

NPC-3000 Series NATM Pressure cells are designed to monitor stress of shotcrete in the construction of tunnels, particularly those using the New Austrian Tunnel Method and other underground works. Monitoring of the radial and tangential stresses within shotcrete linings is vital to its success.

THERMISTOR

In stock

Thermistors provide accurate and reliable long-term temperature measurements and are used widely in the extremely harsh environments found within Geotechnical monitoring. They are available in two types:
  • Probe – A single point sensor mounted within a PVC or stainless steel housing which is attached to a cable length.
  • String – A series of sensors mounted along a multi-core cable which provide a temperature profile and is manufactured to customer requirements in terms of the number and spacing of each sensor.

VW ANCHOR LOAD CELLS VWLC-5000

In stock

The VWLC 5000 series Vibrating Wire Anchor Load Cells consist of a cylinder of high strength steel with 3 to 6 vibrating wire strain sensors (depending on capacity) mounted parallel to the longitudinal axis arranged equidistant around the circumference which measure the compression of the cylinder under load. They are manufactured with a Center hole to accommodate anchors, rock bolts and tendons.

VW LIQUID SETTLEMENT SYSTEM

In stock

The VWLSS-200 Vibrating Wire Liquid Settlement System is used to monitor settlement or heave in soils and other structures such as embankments, earth and rockfill dams. The main components are a reservoir (single or multiple), liquid-filled tubing and a vibrating wire pressure transducer cell mounted on a plate or, for borehole application, attached to an anchor.

NEXUSGEO

In stock

The NexusGEO® is a Bluetooth Interface which can be used to connect a wide range of sensors with analogue or RS-485 digital outputs to an Android smart device for manual readout. This means data can easily be accessed on site by any Android device such as a smartphone or tablet. Specially-developed by Geosense, it is designed to offer interoperability between sensors and the chosen Android device. This enables the user to benefit from the increased processing capability and connectivity of a smart device over a standard readout. The user can simply read and store data or read, store and transmit it via a mobile network.

PT100

In stock

The Pt100 temperature sensor contains a platinum resistance thermometer that changes resistance value as its temperature changes and provides accurate and reliable long-term temperature measurements. These sensors are often used in the extremely harsh environments found within Geotechnical monitoring.  

VW PIEZOMETER VWP-3000 SERIES

In stock

The VWP-3000 Series of Vibrating Wire piezometers use the well-proven method of converting fluid pressures on a sensitive diaphragm into a frequency signal.
