You ﬁnd general recommendations for wiring of eﬀective pressure

lines in DIN 19210 "Eﬀective pressure lines for ﬂow systems" or the

corresponding national or international standards. When wiring

eﬀective pressure lines outdoors, keep in mind to use a suitable

antifreeze, e.g. by using tube heat tracing. Wire eﬀective pressure

lines with a monotonic decrease of at least 10 %.

In case of strong vibrations at the application position, the instrument

version with external electronics should be used.

Higher process temperatures often mean also higher ambient

temperatures for electronics and connection cable. Make sure that the

upper temperature limits stated in chapter "Technical data" for the

environment of the electronics housing and connection cable are not

exceeded.

4.2 Special application conditions

Oxygen and other gases can be explosive with oils, grease and

plastics so that the following provisions must also be taken:

l All components of the plant, such as e.g. measuring instruments

must be cleaning according to the requirements of BAM

(DIN 19247)

l Depending on the materials used, a certain max. temperature and

pressure must not be exceeded in oxygen applications

Danger:

Instruments for oxygen applications must be unpacked just before

mounting. After removing the protective cover of the process ﬁtting, the

label "O₂" will be visible on the process ﬁtting. Penetration of oil,

grease and dirt should be avoided. Danger of explosion!

We also oﬀer oil and grease free instruments for special applications

such as e.g. ultra-pure gas. There are no special restrictions with

respect to the process conditions.
