SAFETY NOTE
A safety isolator such as a zener barrier is always needed for
intrinsic safety.
Probes covered with plastic and/or with plastic discs may generate
an ignition-capable level of electrostatic charge under certain
extreme conditions. Therefore, when the probe is used in a
potentially explosive atmosphere, appropriate measures must be
taken to prevent electrostatic discharge.

SPECIAL CONDITIONS FOR SAFE USE (X)
The intrinsically safe circuits do not withstand the 500 V ac test as
specified in EN 50020 clause 6.4.12.
Probes covered with plastic and/or with plastic discs will have a
non-conducting area that exceeds the maximum permissible areas
for Group IIC and Category II 1G according to EN 50284 clause
4.4.3 (4 cm
2
). Therefore, when the antenna is used in a potentially
explosive atmosphere, appropriate measures must be taken to
prevent electrostatic discharge.
Impact and friction hazards need to be considered according to
EN 50284, clause 4.3.1 when the transmitter exposed to the
exterior atmosphere of the tank is made of light metal alloys, and is
used in Category II 1 G.
