Tranmsitter with Bus technology of Series 5350B manufactured by PR Electronics A/S via the
test made by NEPSI (National Supervision and Inspection Center for Explosion Protection and Safety
of Instrumentation) have been proved that they are fulfilling the General Requirements according to
Article I, GB 3836.1-2000 "Electrical equipment using in the Explosive gas Environment" and the
specified requirements for "i." series in Article IX, GB3836.8-2000. The symbol of explosive
protection are EX ia IIC T4~T6 or Ex ib(ia) IIC T4~T6 while the Certificate No. is GYJ091290X.
Note for the use of transmitter:
1. The Symbol "X" applied after the Cert. No., indicates that this transmitter cannot be applied in
explosive environment of danger until the Protection Grade of the box where the transmitter will later
on be placed is not lower thant IP20 (GB4208), and has been approved by the National Authorized
Inspection Body. The metallic case must accord to item 8, GB3836.1-2000; the nonmetallic case must
accord to item 7.3, GB3638.1-2000.
2. The relationship of the explosive protection ingress, the temperature Code, ambient temperature
and max. output parameter is indicated as follows:
Ex ia IIC
T4: -40°C~+85°C -40°C~+75°C
T5 -40°C~+70°C -40°C~+65°C
T6: -40°C~+60°C -40°C~+45°C
Ui 30V 30V
Li 120mA 300mA
Pi 0.84W 1.3W
3.The max. inner capacitance and max. inner inductance of the transmitter are:
Ci=2nF Li=1 μ H
4. The transmitter in explosion protection system can only be applied in the explosive environment
when it is combined with other Intrinsic safety devices which have also been tested and approved by
the National Authorized Inspection Body and met the requirements of GB3836.1-2000 and GB3836.8-
2000. And this explosion protection system meets the requirements belows:
Uo≤Ui Io≤Ii Po≤Pi Co≥Cc+Ci Lo≥Lc+Li
Note: Cc, Lc are distributed electric capacity parameters of connection cable.
Uo, Io, Po are maximum output parameters of relative devices; Co, Lo are maximum internal
parameters of relative devices.
5. The connection cable between the transmitter and the intrinsically safe port of the associated
equipment is 3-wires electric-shielded cable with the insulating jacket. The sectional acreage of wire >
0.5mm2. Its electric-shield jacket is grounded in non-dangerous area and is insulated with the house of
the transmitter, the cable should be out of the electromagnetic interference.
