At Workswell, we come with a new drones camera system designed to detect dangerous gases. The aim of the system is to provide information on the occurrence of hazardous or noxious gas at a safe distance, using drones. We used standard infrared optical metohod for gas leakage detection - cooled thermal imaging camera.
Thermal imaging camera Workswell GIS-320 can detect a wide spectrum of gases, which are invisible to a human’s eye.
The GIS-320 has a high sensitivity with a cooled MWIR (Midwave Infrared) sensor with a range of detection between 3.2 – 3.4 µm. Cooled quantum detector’s resolution is 320×240 pixels which is a perfect for this thermal camera. This detector operates on a very low temperature which increases its detection capability. Its operating temperature is about -200°C which increases its temperature sensitivity (15mK). This enables it to detect gases of very small concentrations.
Ie. camera is capable to detect gases for instance (at a distance of tens of meters):
Princip of gas detection based on MWRI thermal imaging camera is very well described here.
The dimensions of the camera are 201 x 150 x 105 mm and it weighs under 1.6kg.
