SISTER BAR REBAR STRAIN METER VWS-4000
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.
Description
SISTER BAR: The VWS-4000 Sister Bar is installed by tying it alongside an existing length of rebar within the cage. Available in two diameters: 12 and 16mm.
REBAR STRAIN METER: The VWS-4001 Rebar Strain Meter is installed by welding it into the existing rebar cage at a location within the structure where loads can be accurately passed from the concrete into the gauge. Available in various diameters to match the size of the rebar cage into which it is to be welded.

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.
PRESSURE TRANSDUCER VWT-9000 SERIES
In stock
The Geosense® VWT-9000 Series of Pressure Transducers are designed to be connected directly into hydraulic or pneumatic pressure lines by means of a 1/4” BSPF thread. Other thread sizes are available on request.
They are typically used to monitor uplift pressures within dams and to enable manual standpipe piezometers to be upgraded into an automated data acquisition system.
NANO TRIAXIAL TILT SENSOR
In stock
The Nano range uses the same core platform as our other tilt sensors, so it can deliver a similar level of performance and reliability, all in a small and robust enclosure. Nanos have been successfully used in many applications, including:
- Tunnel distortion
- Tunnel heave/settlement
- Embankment slippage (used in conjunction with stake mounts)
- Structural movement
- Rail track heave/settlement
- Rail trackbed cant and twist

PORTABLE MEMS INCLINOMETER
In stock
The MEMS Portable Inclinometer system utilises modern communication and Smart devices to enable the tilt data generated by the probe to be managed, stored and transferred directly from site via FTP, API, email or other communication platforms.
It is available for vertical, inclined and horizontal applications.
TILT BEAM MEMS
In stock
MEMS Tilt Beams are designed for attachment to structures, on either a vertical or horizontal surface, for the measurement of tilt or differential settlement.
They consist of a highly accurate MEMS sensor housed in a fully sealed enclosure which is mounted on a lightweight rigid GRP beam. This can be mounted onto the structure using special anchors. The GRP beam has a very low coefficient of thermal expansion meaning that thermal affects are minimised.
MAGNETIC EXTENSOMETER GXM RANGE
In stock
The GEO-XM settlement system is a magnet extensometer system used typically to monitor settlement and heave in foundations, excavations and embankments.
Data received identifies the depth and position where settlement has occurred as well as the total amount of settlement.
It can also be installed behind retaining structures, such as sheet piles and slurry walls, and above underground openings, such as tunnels and shafts.
