Geosystems: Geotechnical Crackmeters and Jointmeters
d-Micro Geotechnical Crackmeter
The highly versatile d-Micro crackmeter is ideal for monitoring cracks in underground mines, parking garages, dams under rehabilitation, residential buildings, bridge decks, and pillars or posts.
d-Micro crackmeters output readings in degrees C and microns eliminating the necessity for expensive analog-to-digital conversions. Readings can be made using the USB port of a laptop or tablet computer (SensorViewer).
Long term, low power, data logging is possible using the low-cost dLoggers.
A Real-time plug-and-play network of d-Micro sensors or any combinations of any other YieldPoint Instruments can be built in minutes using the IoT Gateway or d-Mesh.
Fibre Optic Displacements Sensor (FOD)
The FOD optic linear position and displacement transducer is an absolute position transducer that provides highly precise position and displacement measurements. Ideal to monitor deformation in structures over a longer-term. The sensor is able to monitor deformations over joints and cracks.
Uniaxial and Triaxial Surface Joint Fissuremeter
The RTF is a jointmeter which measures the displacement of cracks in structures of rock masses. The jointmeter is designed to monitor the relative movement of adjacent surfaces across cracks or conjunction joints. The RTF crackmeter (fissuremeter) is available as a uniaxial (RTF-1D) and triaxial (RTF 3D).
The Tell-Tails is a basic, easy to use crackmeter. The adhesive backings stick either side of a crack. As the crack develops the two scales on the Tell-Tails indicate the cracks’ movement.
