Introduction
The turbidity sensors METTLER TOLEDO InPro 81XX/82XX */*/*/* may be
used in accordance with EN IEC 60079-0:2018 and EN60079-28: 2015 in
the categories 1 to 3 (Zones 0 to 2) and gas groups IIA and IIB only accord-
ing to above (see Ex-classification) stated max. temperature specifications.
Special conditions X
1. The turbidity probes InPro 8100/*** and InPro 8200/*** may only be
used with the transmitter Trb 8300 (phased out) or M800 1-channel.
These transmitters, not situated in the explosive atmosphere but con-
taining the light source (LED) are associated apparatuses which have
a specified ambient temperature range from –10 °C to + 50 °C.
2. Outside the tank/vessel in which the probe is located, the ambient
temperature range is: – 20 °C ... + 60 °C.
3. The maximum permissible temperature (a.k.a. limiting temperature)
of the process medium in which the probe is located (inside the tank/
vessel) determines the probe maximum surface temperature. These
temperatures should be considered as follows:
Gas group
IIA
IIB
4. The metal body of the turbidity probes (resp. safety shrink-wrapped
nozzle, fittings InFit
tively connected to the equipotential bonding system of the installation.
5. The metal body of the turbidity probes (resp. safety shrink-wrapped
