used and follow the specifications of the following documents:
l
this operating instructions manual
l
this manufacturer declaration (24646)
l
the applicable installation regulations
Max. increase of the surface temperature during operation:
40 K (individual components in the instrument)
With an ambient temperature of 70 °C (158 °F) on the housing
and a process temperature of 70 °C (158 °F), the max. ambient
temperature during operation is 110 °C (230 °F).
Measures to maintain explosion protection during operation:
l
Operate the instrument in the range of the specified
electrical limit values. Permissible supply voltage: see
"Technical data"
l
Mount and operate the instrument in such a way that no
ignition danger is expected by electrostatic charges. The
process fitting, the plastic-coated/covered probe part or the
housing are made of electrically non-conductive plastic
(depending on the version).
l
Make sure that the seal is mounted correctly between
lower part of the housing and cover. Screw the cover on
tightly.
l
Make sure there is no explosive atmosphere present if you
intend to operate the instrument with opened cover
l
Make sure that the cable gland is tight and strain-relieved.
The outer diameter of the connection cable must be
adapted to the cable gland. Tighten the pressure screw of
the cable gland carefully.
l
Cover unused openings for cable glands tightly
l
Mount the instrument in such a way that the sensor cannot
touch the vessel wall or vessel installations. Keep in mind
the influence of product movement in the vessel.
l
The surface temperature of the housing must not exceed
the ignition temperature of the surrounding explosive
atmosphere
This instrument was assessed by a person who fulfils the DIN
