7. Starting, operation
Protect the diaphragm against any contact with abrasive substances and
„
pressure peaks and do not touch it with tools. If you damage the diaphragm,
no intrinsic safety can be guaranteed (ATEX)!
Warning
Ensure that under hazardous dust ennvironment the pressure sensor is
„
mounted in a shielded section and protect it against shocks.
Observe the technical data for the use of the pressure sensor in connection with aggres-
„
sive/corrosive media and for the avoidance of mechanical hazards.
Installation in / mounting to zone 0 and zone 20 (zone 20 not with PEX15)
(In general Zone 0 is given when the pressure sensor is surrounded by a mixture of
explosive gases more than 1.000 hours per year = continuous hazard).
When installing the pressure sensor or the cable gland into areas whic
„
require category 1G equipment, ensure that ingress protection IP67 accor-
ding to IEC 60 529 is guaranteed.
Warning
When installing the pressure sensor or the cable gland into areas which
„
require category 1D equipment, ensure that ingress protection IP 6X accor-
ding to IEC 60 529 is guaranteed.
Measurement of process media with higher temperatures than the media temperature ranges
specified in the tables of the EC-type examination certificate under item 15.1.2 is permissible, if
special cooling elements are used (not for PEX15).
Observe the permissible surface temperature applicable for this range
„
according to the defined temperature classes.
Observe the maximum temperature value (of the temperature range defined
„
Warning
under item 15.1.2 in the EC-type examination certificate) at the hexagon of
the tubular case.
Ensure an unhindered air circulation at the cooling element.
„
Protect the pressure sensor against touching or affix a warning notice.
„
Insulate heat sources thermally from the pressure sensor (e.g. pipes or tanks).
