transmitter.
Use as a resource belonging to Category 1/2:
The pressure transmitters can be mounted in the wall separating the area with Category 1
requirements (Zone 0) and the area with Category 2 requirements (Zone 1). In this case, the
process connection must be adequately sealed in compliance with IEC/EN 60079-26, Clause 4.3,
for example by providing degree of protection IP67 in compliance with EN60529. The supply
must be effected via intrinsically safe circuits with type of protection ia. The measuring cell may
only be used for flammable materials to which the diaphragms of the measuring cells are
adequately resistant both chemically and in terms of corrosion.
4.3
Installation
• The location of the device has no influence on the measurement accuracy.
• Before installation, compare the process data with the data of the rating plate.
• The medium being measured must be suitable for the parts of the pressure transmitter in
contact with the medium.
• The overload limit must not be exceeded.
• Connect the devices with fixed cable installation.
• High-frequency electromagnetic interferences may result in measurement deviations of up
to 1%.
