WiMo Calibration Tool
In stock
The usb tool allows to connect a WiMo sensor to a computer to calibrate the sensor independently of a WiMo sonde. It works with a dedicated software named “WiMo Calibration Tool”.
You will be able to:
- Connect any WiMo sensor to a computer
- Check its configuration
- Calibrate your sensor
- Make some measurement
VW STRAIN GAUGE EMBEDMENT VWS-2100
In stock
The VWS-2100 series vibrating wire embedment strain gauges are designed for direct embedment in concrete.
The strain gauge operates on the principle that a tensioned wire, when plucked, vibrates at its resonant frequency. The square of this frequency is proportional to the strain in the wire.
The gauge consists of two end blocks with a tensioned steel wire between them. Around the wire is a magnetic coil which when pulsed by a vibrating readout or data logger interface plucks the wire and measures the resultant resonant frequency of vibration.
VW STRAIN GAUGE SPOT WELD VWS-2020
In stock
The VWS-2020 series vibrating wire strain gauges are designed primarily to measure strains on the surface of steel structures but may also be used on other types of material.
The gauge consists of two end blocks with a tensioned steel wire between them. The end blocks are attached to stainless steel tabs which may be attached to steel structures by spot welding or, using alternative end blocks, bonded or grouted.
Precision tensioning is carried out on site using a special tensioning jig and the gauge can be set for compression, tension or at mid-point.
VW STRAIN GAUGE STRAND ANCHOR VWS-2800
In stock
The VWS-2800 vibrating wire strain gauge is designed for the monitoring of strain along stranded anchors.
The gauge is housed within a robust cover to de-bond it from the surrounding grout and the specially-designed mounting blocks ensure the strain is transferred from the strand to the gauge. The low profile design means that multiple sensors can be installed along the bonded length of strand anchors.

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.
MLBase
In stock
The MLBase™ is a communications base station for the MLRemote® wireless datalogging system. The MLBase provides for queuing all inbound and outbound data communications with MLRemote.
Network communication options for the MLBase include both Wi-Fi and Cellular integration. The MLBase offers long-distance communications and low power in a small form factor when paired with the MLRemote. Low-data rate communications of up to 15 kilometers (9 miles) is achievable, and up to 100 kilometers (60 miles) with the use of gain antennas.
NATM PRESSURE CELLS NPC-3000
In stock
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.
