Fire smoke detector linear explosion-proof. Distinctive features of this modification: single-position version; operating distance from 8 to 60, to 80, to 100 metres; the detector has the explosion protection marking "0Ex ia II CT6 Ga" and intrinsic safety parameters: "Li: 1 µGn, Ci: 1000 pF, Ui: 30 B, Ii: 25 mA, Pi: 0.75 W"; reflector IPDL-Ex has the explosion protection marking "II Ga T6 X".
??212-75?? is a single-position linear explosion-protected fire detector consisting of a transceiver, hermetic enclosure and reflector reflector.
In the transceiver, the optical channels are separated and isolated in a two-chamber optical system. As a reflector-reflector in ??212-75??
a highly effective cataphone (light-reflector) is used, which is able to fulfil its functions even if its surface is deflected relative to the optical beam by 10 - 15 degrees. The output pads and the switch for setting the tactics of operation are located in the hermetic box.
