Transmitter ex-proof parameter:
Ui=28VDC Ii=93mADC
Li=0mH Ci=0.044μF Pi=0.65W
When the product is using under "zero" area, the power transformer to
the safe barrier shall meet
GB3836.4-2010.
The biggest permitted distributed capacitance for the cable between the
transmitter and safe barrier connection is Cc=Co-Ci, the biggest
permitted distributed inductance Lc=Lo-Li.
Users can buy a safe barrier by yourself, only need to take care its specs
are as above-mentioned requirements and have an explosion-proof
certificate. The installation of safe barrier is in accordance with its
operating instructions.
4.5 Explosion proof explosion-proof transmitter
a) There should be ExdⅡCT6 sign on the transmitter explosion proof
name board; Explosive mixture used at the place should be in
accordance with corresponding level stipulated.
