FIBER OPTIC - TECHNOLOGIES

Fiber Optic Technologies • Fabry-Perot Interferometer (FISO):

These point sensors measure local strain, temperature, pressure and displacement. These values are encoded in a change of length of an optical cavity within the sensors that can be measured accurately. Fabry-Perot sen-sors offer excellent long-term stability. They are the ideal optical replacement for conventional geotechnical sensors.

• Low-Coherence Interferometers (SOFO):

These long-gauge sensors measure displacement or average strain over measurement bases that can extend up to several meters. They are ideal transducers for monitoring concrete and geotechnical structures. Defor-mations are measured by observing the length changes of an optical fiber attached to the structure under ob-servation, compared to a loose reference fiber. This measurement principle allows accurate and stable meas-urements and insensitivity to temperature variations.

• Fiber Bragg Grating (MuST):

FBG sensors are written in the optical fiber core and act as optical filters, reflecting the wavelength that match-es the grating pitch. The reflected wavelength depends on the strain and temperature of the grating, enabling measurement of those two parameters and others that can be transformed to strain (deformation, tilt and accel-eration). It is possible to combine multiple gratings with different reflective wavelength on the same fiber (multiplexing).

• Distributed Raman Scattering (DiTemp):

These sensors use an intrinsic property of optical fibers to measure the local average temperature of each me-ter of fiber for lengths up to several tens of kilometers. This enables the measurement of thousands of tempera-tures along a single cable. This technology is particularly suitable for detecting and localizing hot or cold spots associated with leaks or other defects.

• Distributed Brillouin Scattering (DiTeSt brand):

This technology is similar to Raman scattering, but offers the additional ability to measure distributed strain. This enables the detection of local events such as settlements, deformations, cracks and movements.

VANE BORER M1000

The M1000 Vane Borer is a precision field instrument which consists of a torque recording head, boring rods, specially designed vanes, and a slip coupling. The head measures and records vane resistance, rod friction and angu-lar rotation. The system is supported by a torque head casing adaptor.

FIELD INSPECTION VANE TESTER H-60

The H-60 Field Inspection Vane Tester is used to provide a rapid check of the stability of foundations, excavations and trenches in clay. It enables quick and easy determination of the undrained shear strength of clay. The instru-ment is strong enough to be used as a handle during penetration and retraction of the vane.

PENETROMETER HSA-5

The HSA-5 Handheld Static Penetrometer was designed to make soundings to limited depths by the “Dutch Cone Static Penetrometer” method with a single string of rods.

PENETROMETER PEM-1

The PEM-1 Penetrometer is designed to per-form in situ dynamic penetration tests. This equipment consists of a hard steel stem with a cone shaped end and is inserted into the ground under the action of a falling mass. The PEM-1 is a compact and rugged piece of fieldequipment.

The PIL-7 Point Load Tester is designed to determine the point load strength index. This index provides a method to establish rock strength classification. The PIL-7 is a rugged system armoured with a shield for protection from flying chips upon failure. It is portable and durable and comes with conical platens.

The G-200 Fall Cone Apparatus is used to provide a quick and accurate method for deter-mining the undrained shear strength and the sensitivity of both undisturbed and remolded clays. This system is portable, fast, accurate and easy to use. It is also used to determine the liquid limits (fineness number).

The Hoek Triaxial Cell is designed to deter-mine the triaxial strength of diamond drill cores of rock or concrete. Tests carried out on a series of samples under different confining pressures allow the user to determine the strength and elastic properties, the shear strength at different confining pressures, the angle of shearing resistance, the cohesion, the modulus of elasticity and Poisson’s ratio.
