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 ush 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 specications contained in these operating instructions must be observed. Improper handling or
operation of the pressure transmitter outside of its technical specications 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.

4. Design and function / 5. Transport, packaging and storage
4. Design and function
4.1 Description
The prevailing pressure is measured at the sensor element through the deformation of a diaphragm. By supplying
power, this deformation of the diaphragm is converted into an electrical signal.The output signal from the pressure
transmitter is amplied and standardised. The output signal is proportional to the measured pressure.
4.2 Scope of delivery
Cross-check scope of delivery with delivery note.
5. Transport, packaging and storage
5.1 Transport
Check the pressure transmitter for any damage that may have been caused during transportation.
Obvious damage must be reported immediately.
5.2 Packaging

6.2 Electrical mounting
■
The instrument must be grounded via the process connection.
■
For instruments with voltage output, use shielded cable, and ground the shield on at least one end of the lead, if the
lines are longer than 30 m or leave the building.
■
In North America, use the instrument in line with “class 2 circuits” or “class 2 power units” in accordance with CEC
(Canadian Electrical Code) or NEC (National Electrical Code).
■
Select a cable diameter that matches the cable bushing of the connector. Make sure that the cable gland of the
mounted plug has a tight t and that the seals are present and undamaged. Tighten the threaded connection and
check that the seal is correctly seated, in order to ensure the ingress protection.
