Geotextile Monitoring
FOS & S Geotextile Strain Sensor

A geotextile equipped with optical fibres to measure strain and designed to increase the safety of civil engineering infrastructure.

 

Temperature
FOS & S Fibre Temperature Chain Sensor

A chain of FBG sensors protected from stress by a stainless steel capillary. The length, number of sensing points and their spatial distribution can all be specified.

FOS & S Temperature Sensor Probe

A single FBG sensor mounted in the end of a 3mm capillary can measure temperature with a resolution of 0.1C and an accuracy of 1C.

FOS & S Fibre High Accuracy Temperature Sensor Probe

Connectorised at both ends to enable series configurations and mounted in a 6mm capillary, a single FBG sensor can measure temperature with a resolution of 0.04C and an accuracy of 0.4C.

FOS & S Fibre Distributed Temperature Sensor

A stress free distributed sensor mounted in a 1.5mm capillary can measure temperature over the whole length.

 
Strain
FOS & S Fibre Embeddable Strain Sensor

A single prestrained FBG sensor in a ruggedised housing that can be embedded in a material (such as concrete) to measure both extension and compression.

FOS & S Bare Fibre Mountable Strain Sensor

A single high strength coated FBG sensor for direct mounting (gluing).

FOS & S Prestrained Fibre Mountable Strain Sensor

A single prestrained FBG sensor in a ruggedised housing that can be anchored at each end to measure both extension and compression.

FOS & S Fibre Mountable Strain Gauge

A high strength Draw Tower Grating (DTG) that can be mounted directly onto a surface using the SGK-01 Installation Kit

FOS & S Fibre Strain Gauge Installation Kit

Developed for aircraft standard installation of strain gauges (SG-01) onto various metallic and composite surfaces.

 
Strain Cable
FOS & S Bare Fibre Chain Strain Sensor

With lengths of 1~5m, the distributed strain monitoring is possible with a resolution of 1ε and an accuracy of 0.5%.

 
Displacement
FOS & S Sliding Casing Displacement Sensor

A temperature compensated FBG sensor is mounted in a sliding mechanism capable of measuring displacement up to 8cm with a resolution of 0.05% and an accuracy of 1% full scale.

FOS & S Sliding Pin Displacement Sensor

An FBG sensor is mounted in a sliding mechanism with spring loaded pin and is capable of measuring displacement up to 8cm with a resolution of 0.05% and an accuracy of 1% full scale and temperature.

FOS & S Fibre Distributed Strain Sensor

A prestrained distributed sensor mounted in a 1.5mm capillary can measure extension and compression over the whole length.

 
Pressure
FOS & S Fibre Non-Porous Pressure Sensor

Using the internal strain sensitivity of an FBG this sensor has a threaded head that can measure pressure in vessels, valves or pipelines.

 
Load Cells
FOS & S Fibre Pressure Converter

By converting load into pressure, this device measures load to 0.1% resolution and 1% accuracy full scale.
