2.9 Applied Ex-Rules
The type 86-EX instruments are built and certified for applications in the
following EX-Zones and protection Classes:
Probes: Tubes and tips of the probes may be used in Zones 0.
Electronics of probes and connection cables may be used in Zones 1.
Protection Class is EEx ia IIC T4. ATEX-Category for probes is 2G or 2D,
eventually also 1G or 1D, but then a certification of each single instrument
must be done by the proofing authority. Maximum surface temperature of
probe housing and intrinsically safe connection cables is restricted to
60°C.
