Description

The model SA-11 pressure transmitter is designed especially for the requirements of the food and beverage, pharmaceutical and biotechnology industries.
The instrument 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 joint between the process connection and the measuring cell, additional sealings are not required.
For dead-space free instrumentation, aseptic process connections (clamp, threaded, VARIINLINE® and NEUMO®) are available.

The model SA-11 conforms to the 3-A Sanitary Standard and is EHEDG-certified.

Construction
A diaphragm made of 1.4435 stainless steel forms a flush separation of the process medium from the pressure transmitter.
The process pressure is transmitted hydrostatically from the diaphragm, via an FDA-approved system fill fluid, to a piezoresistive sensor.
The measuring range covers 0 ... 250 mbar up to 0 ... 25 bar.
The model SA-11 pressure transmitter is powered with a DC voltage of 10 (14) ... 30 V. As output signals, 4 ... 20 mA, 0 ... 20 mA or 0 ... 10 V are available.

A stainless steel case, with an ingress protection of up to IP68, offers a secure protection for external cleaning with splash water and enables its use in high-humidity environments. Through the integrated cooling element, process temperatures of up to 150 °C [302 °F] can be realised.
