Conditions of Certification
The intrinsically safe circuits do not withstand the 500V AC test as specified in
EN 50020 clause 6.4.12.
Impact and friction hazards need then to be considered according to IEC
60079-0 clause 8.1.2 when the transmitter and part of antennas exposed to
the exterior atmosphere of the tank is made with light metal alloys and used in
Zone 0.
Parts of the rod-antenna and the All PTFE antenna are non-conducting and
the area of the non-conducting part exceeds the maximum permissible areas
for Group IIC according to IEC 60079-1 clause 7.3: 20 cm
2
for Zone 1 and 4
cm
2
for Zone 0. Therefore, when the antenna is used in a potentially explosive
atmosphere, appropriate measures must be taken to prevent electrostatic
discharge.
