Description

The SA-11 pressure transmitter has been specially designed to meet the requirements of the food, beverage, pharmaceutical and biotechnology industries. With its resistance to chemical cleaning liquids and high temperatures, this transmitter is particularly suited for CIP/SIP cleaning processes.
The flush diaphragm is directly welded to the process connection, thus ensuring a gap-free connection and eliminating the need for additional sealing gaskets. In order to provide a pressure measuring instrument which is free of dead spaces, a wide range of aseptic process connections (Clamp, threaded, VARIVENT® or NEUMO®) are available.
The SA-11 pressure transmitter meets the high requirements of sterile engineering processes and is certified in accordance with the 3-A Sanitary Standards and the EHEDG.

Structure
A flush diaphragm of stainless steel 1.4435 separates the process medium from the pressure sensor.
The process pressure is hydrostatically transmitted from the diaphragm to a piezo-resistive sensor via a filling fluid approved by the FDA.
Pressure ranges of 0 ... 250 mbar up to 0 ... 25 bar are available. The pressure transmitter SA-11 is supplied by DC 10 (14) ... 30 V.
Electronic output signals 4 ... 20 mA, 0 ... 20 mA and 0 ... 10 V outputs are available.
A stainless steel case with an ingress protection of up to IP 68 provides enough protection to enable external cleaning with a water jet or the use in high humidity environments.
