2.5 Instructions for temperature ranges
2.6 Special instructions for dust explosion protection
Observe the permissible surface temperatures applicable for this range according
to the defined temperature classes.
Observe the maximum temperature value (of the temperature range defined under
item 15.3. in the EC type test certificate at the hexagon of the process connection.
Protect the pressure transmitter against touching or affix a warning notice.
Insulate heat sources thermally from the pressure transmitter (e.g. pipes or tanks).
Ensure that under hazardous dust environments the pressure transmitter is moun-
ted in a shielded section and protect it against shocks.
When installing the pressure transmitter or the cable gland into areas which require
category 1D equipment, ensure that ingress protection IP 6X according to IEC 60
529 is guaranteed.
Observe the EN 50281-1-2 in relation to e.g. dust deposits and temperature.
The permissible ambient temperatures as well as the maximum surface tempera-
tures are to be taken from the EC type test certificate.
