 Embedded
FBG Strain Sensor |
|
The embedded strain
sensor is composed of one or more FBGs. The FBG
is bonded with a solid structure, which makes it
easy to measure both extension and compression.
The sensor can be directly embedded into concrete
structure, soil, or rock, and it is easy to be arranged
in a rosette configuration for multi-dimensional
sensing, due to the small size of the sensor.
Applications:
Strain monitoring, concrete, solid rock, or soil
monitoring.

| LCWIMS
Fiber Optic Weigh-In-Motion (WIM) Sensor System |
|
| Weigh-in-motion
(WIM) devices are designed to capture and record
vehicle axle weights and gross vehicle weights
as they drive over a sensor. Unlike older static
weigh stations, the presentWIM systems do not
require the subject vehicles to stop, making them
much more efficient. This system can acquire real-time
data on highway vehicles (numbers, weight, type
and density of traffic) and road and weather conditions
such as icy roads, fog, rain, snow, etc. Gross
vehicle and axle weight monitoring is useful in
an array of applications including:
• Pavement design, monitoring, and research,
• Bridge design, monitoring, and research,
• Size and weight enforcement,
• Legislation and regulation,
• Administration and planning.
Portable Fiber Optic WIM System:
Current WIM systems mainly include piezoelectric
system, bending plate system and load cell system,
etc. These methods have several disadvantages,
such as low operation speed (<10 mph) , largeinstallation
space, expensive Initial installation cost and
maintenance cost. The prototype of this portable
fiber optic WIM sensor system can be employed
to accurately measure the axle and wheel weights
of sedans, light trucks, and heavy trucks that
are moving at speeds of 5 mph to 30 mph. The specifications
are shown as follows,
Speed: 5~ 30 mph
Sensitivity: <10 lbs
Maximal weight of measured vehicles: 10 T (others
available upon the customer's requests)
System accuracy: 1 ~ 5%
Self-weight of sensor heads: 100 kg.

Bragg Grating Pressure Sensor |
|
Description
The down-hole fiber optic pressure sensor uses a
Fiber Bragg grating (FBG) embedded with a novel
material to convert pressure into measurable strain.
Under the applied pressure environment, the embedded
material will contract, correspondingly, the Bragg
wavelength of FBG will shift. By measuring the Bragg
wavelength shift, the applied pressure can be derived.
The sensor is also sensitive to temperature changes.
In order to compensate these influences a reference
temperature sensor is utilized. The rugged design
allows it for harsh environment application.
Applications
Monitor pressure especially in harsh down-hole environment
with high pressure and high temperature in the oilfield.
Features
Large pressure measurement range, high sensitivity,
high working temperature, temperature compensation,
small size, easy to install.
