Transmitter ex-proof parameter:
Ui=26VDC Ii=140mADC
Li=0mH Ci=0.055μF Pi=0.66W
Please pay attention that the max. available distributing capacitance for
connected cable between transmitter and safe barrier is C
max. available distributing inductance is L
Safe barrier could be purchased by user freely. As long as the safe
barrier comply with the above requirement and owns Qualified Certificate,
it can be used with transmitter together.
Please install and operate safe barrier as operation manual indicates.
4.3.2 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.
b) Transmitter installation should meet the requirement as below:
1) The cap must be tightened, and there are at least 6 joggles.
Do not damage the thread.
2) The explosion proof's construction and components of Exd
