Description
The pressure transmitter SA-11 is designed especially for the requirements of the food and beverage, pharmaceutical and biotechnology industries.
It is particularly suitable for the special conditions of CIP/SIP cleaning processes, such as chemical stability towards cleaning liquids and high temperatures.
The flush diaphragm is directly welded to the process connection. This guarantees a crevice-free connection of the process connection and the measuring cell so that additional sealings are not required. For dead-space free instrumentation, aseptic process connections (clamp, threaded, VARIVENT ® and NEUMO®) are available.
The SA-11 pressure transmitter is ideally suited to fulfil the stringent demands of sanitary applications and is EHEDG certified. Furthermore, the SA-11 is marked with the 3-A symbol and current version number, as it conforms, based on a third party verification, to the 3-A standard.
Design
A diaphragm made of 1.4435 stainless steel forms a flush separation of the process medium from the pressure measuring instrument.
The process pressure is transmitted hydrostatically from the diaphragm, via an FDA-approved system fill fluid, to a piezo-resistive sensor.
The measuring range covers 0 … 250 mbar up to 0 … 25 bar.
The SA-11 pressure transmitter is powered with a DC voltage of 10 (14) … 30 V. Available electronic output signals are 4 … 20 mA, 0 … 20 mA or 0 … 10 V output.
A stainless steel case with an ingress protection of up to IP 68 offers a secure protection for external cleaning with splashed water and enables its use in high-humidity environments. Through the integrated cooling section, process temperatures of up to 150 °C can be realised.
