Introduction
The turbidity sensors METTLER TOLEDO InPro 81XX/82XX */*/*/* may be used
in accordance with EN60079-0: 2012 and EN60079-28: 2007 in the cat-
egories 1 to 3 (Zones 0 to 2) and gas groups IIA and IIB only according to
above (see Ex-classification) stated max. temperature specifications.
Special conditions X
1. The turbidity probes InPro
be used with the transmitter Trb 8300 or M800 1-channel. These
transmitters, not situated in the explosive atmosphere but containing
the light source (LED) are associated apparatuses which have a spec-
ified 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 noz-
zle, fittings InFit
nected to the equipotential bonding system of the installation.
