Vibrating Wire Sensor Node
In stock
Our vibrating wire sensor interface enables high precision and low power monitoring of a wide range of structural and geotechnical sensors for use in variety of sectors.
The Vibrating Wire Sensor interface range brings a wide variety of vibrating wire sensors into our systems. It is a highly integrated system which is capable of exciting and sampling vibrating wire sensors and reporting measurements through Senceive’s wireless communications network to a gateway.
Examples of the sensors supported:
- Piezometers
- Strain gauges
- Load & pressure cells
- In place inclinometers
- External temperature
- Extensometers
- Crack gauges
- Soil moisture sensors
WEIR MONITOR VWM-2000
In stock
The Geosense® VWM-2000 vibrating wire precision water level monitor utilises a vented vibrating wire force transducer in combination with a cylindrical weight suspended from it to monitor water levels.
The vibrating wire transducer is vented to atmosphere so that any atmospheric changes are automatically compensated.
Crack Sensor Node
In stock
The Crack Sensor Node is used to monitor structural movement including pile separation, crack movement and expansion joint movement.
The Crack Sensor Node interfaces to a linear displacement sensor. It's high precision sampling circuit powers the sensor and reports its measurements through Senceive’s wireless communications network to a Gateway. It has been successfully used in many applications, including those measuring:
- Crack movement
- Pile separation
- Structural movement
- Expansion joint monitoring

VW STRAIN GAUGE SURFACE MOUNT VWS-2000
In stock
The VWS-2000 series vibrating wire surface strain mount gauges are designed for the long term monitoring of steel or concrete structures. Gauges may be attached to steel structures by arc welding or, using alternative end blocks, bonded or grouted into 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.
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.
