VW PIEZOMETER VWP-3000 SERIES
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.
FEATURES
- Reliable long-term performance
- Rugged, suitable for demanding environments
- High accuracy
- Insensitive to long cable lengths
Description
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.
Frequency signals are particularly suitable for the demanding environment of Civil Engineering applications, since the signals are capable of long transmission distances without degradation, tolerant of wet wiring conditions and resistant to external electrical noise.
Key applications include measuring pore pressure in soils and rocks and fluid pressures in hydro-fractures and pump tests.
Models in the VWP-3000 range are:
- VWP-3000 (STANDARD) Standard construction with high & low air entry filters to measure groundwater elevations and pore pressures.
- VWP-3310 (STANDARD VENTED) Standard construction but vented to compensate for barometric pressure changes. Available with high & low air entry filters.
- VWP-3100 (HEAVY DUTY) Heavy duty body for direct burial in fills and dam embankments. Available with high & low air entry filters, standard and heavy duty cable.
- VWP-3200 (LOW PRESSURE) Low pressure version to measure groundwater elevations and pore pressures. Available with high & low air entry filters.
- VWP-3300 (LOW PRESSURE VENTED) Low pressure vented version to compensate for barometric pressure changes. Available with high & low air entry filters.
- VWP-3400 (DRIVE-IN) Drive-in version available for use with SPT rods.
- VWP-3401 (DRIVE-IN) Drive-in version available for use with 1” BSP adaptor.

IPX IN-PLACE EXTENSOMETER
In stock
The In-Place Extensometer (IPX) offers automated monitoring of standard magnetic extensometer installations. The system is designed for a simple, adaptable installation with a single cable connection at the top of the borehole. Its large measurement range accommodates large levels of settlement or heave, and ease of adjustment means it can be reconfigured for changed site conditions such as embankment filling or cutting.
VWPHT-3600 SERIES
In stock
The VWPHT-3600 series High Temperature Piezometers are suitable for the extreme environments of temperature and pressure found within applications such as geothermal heat and enhanced oil recovery systems including steam assisted gravity drainage (SAGD) and cyclic steam stimulation (CSS). They are capable of monitoring high temperatures up to 250°C and pressures up to 34.5 MPa.

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.
PENDULUM SYSTEM
In stock
HPS-3500 (Hanging) and IPS-3000 (Inverted) Pendulums are used to measure the tilt or rotation by measuring the relative internal horizontal displacement of points along a true vertical line. Each has a tensioned, stainless steel wire and the effects of the earth gravitational forces to guarantee a perfectly vertical line between a fixed point and a tensioning mechanism. Typical applications include concrete dams, bridges and high rise buildings.
HUMIDITY & CORROSION (CorroDec®2G)
In stock
The structural infrastructure must always meet requirements such as performance, stability and durability. These requirements will have a lasting effect on our mobility in the future. The corrosion risk and the corrosion activity of the reinforcing steel largely define these requirements and are determined by various impact and material parameters.
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.
