2.1 Intended use

The model SA-11 pressure transmitter is designed especially for the requirements of the food and beverage,
pharmaceutical and biotechnology industries.
The model SA-11 pressure transmitter is particularly suitable for the special conditions of CIP/SIP cleaning processes,
such as chemical stability towards cleaning liquids and high temperatures. The flush metal measuring cell is directly
welded to the process connection. This guarantees a crevice-free joint between the process connection and the
measuring cell, additional sealings are not required.
The instrument has been designed and built solely for the intended use described here, and may only be used accor-
dingly. The technical specifications contained in these operating instructions must be observed. Improper handling or
operation of the pressure transmitter outside of its technical specifications requires the instrument to be taken out of
service immediately and inspected by an authorised WIKA service engineer.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.
2.2 Compliance with 3-A conformity
For a 3-A-compliant connection the following sealings have to be used:
For milk thread fittings per DIN 11851, suitable profile sealings have to be used (e.g. SKS Komponenten BV or Kiesel-
mann GmbH).
For fittings per IDF sealings with support ring per ISO 2853 have to be used.
Note: Connections per SMS, APV RJT and NEUMO Connect S are not 3-A-compliant.
