2.3 Operational safety
Note the following points:
• Measuring devices for use in hazardous environments are accompanied by separate "Ex
documentation", which is an integral part of these Operating Instructions. Strict compli-
ance with the installation instructions and ratings as stated in this supplementary docu-
mentation is mandatory.
The symbol on the front of this supplementary Ex documentation indicates the approval
and the certification body (e.g.
0
Europe,
2
USA,
1
Canada).
• Burn hazard! When hot fluid passes through the measuring tube, the surface temperature
of the housing increases. In the case of the sensor, in particular, users should expect tem-
peratures that can be close to the fluid temperature. If the temperature of the fluid is high,
implement sufficient measures to prevent burning or scalding.
• The measuring device complies with the general safety requirements in accordance with
EN 61010-1, the EMC requirements of IEC/EN 61326, and NAMUR recommendation
NE 21, NE 43 and NE 53.
• The separate document on the Pressure Equipment Directive must be observed for mea-
suring devices used in Category II or III installations in accordance with the Pressure Equip-
ment Directive.
• The manufacturer reserves the right to modify technical data without prior notice. Your
Hauser sales center will supply you with current information and updates to
these Operating Instructions.
