2) Notice: Gases which react with moisture will not repeatedly pass
through the wire mesh, if the transmitter is installed in a non-
climate controlled environment. If it can be ensured, that
condensation on the wire mesh will not occur; all sensors can be
used in the explosion proof versions 4544120, 4544122.
Otherwise, these sensors should only be used with Polytron 5000
General Purpose 4544165.
