Description
ESA UV-2
Đầu dò UV High sensibility probes UV-2 Esa Pyronics
The UV2 is a flame detector for industrial use installed in a robust, die-cast aluminium box, equipped with plug in connection and threaded connection for the peepsight. It contains a gas filled UVtube. UV-rays (not daylight or artificial light from discharge or filament lamps) ionise the gas in the tube. Figure 1 shows the curb of the spectral response. The UV2 may be used either with all the electronic systems ESA produces or with any other system provided the tube is operated within its limits.
