Industrial Applications
The C330M-G gas leak detection cooled MWIR thermal imaging detector
is used for customers who have strong development ability. By
integrating this cooled thermal sensor, the invisible VOCs
(volatile organic compounds) can be detected and visualized so that
further damage can be avoided. These gases includes such as:
Methane, Ethane, Propane, Butane, Pentane, Hexane, Heptane, Octane,
Ethylene, Propylene, Isoprene, Methanol, Ethanol, Butanone,
Benzene, Toluene, Xylene, Ethylbenzene etc.
About Global Sensor Technology
1.What is NETD?
NETD refers to "Noise Equivalent Temperature Difference". It is a
measure for how well a thermal imaging detector is able to
distinguish between very small differences in thermal radiation in
the image. NETD is typically being expressed in milli-Kelvin (mK).
Usually the lower the NETD figure is, the higher the thermal
sensitivity indicates.
2. What is SWaP3?
SWaP3 refers to size, weight, power, performance and price. It
indicates the technology trend of infrared industry.
3. What is DRI?
DRI usually refers detection, recognition and identification
distance of a thermal imaging system. It is a crucial parameter to
judge the performance of the thermal imaging system.
4. How to select right pseudo color for thermal imaging?
- The gray white is more suitable for the target with small
temperature difference
- The red and blue is more suitable for the scene where the problem
points need to be found.
- The iron red is the standard color palette of the power industry.
Note: no matter which palette you choose, the thermal temperature
will not change at all.
