Diaphragm pressure gauge, flush
Description
The model PG43SA-S diaphragm pressure gauge has been specifically designed for the requirements of sanitary applications.
The purely mechanical pressure transmission, using the diaphragm-element measurement principle, and the high overload safety ensure a safe pressure measurement. As a result of the dry measuring cell, the risk of contamination of the product by transmission fluid is eliminated. The flush welded diaphragm element in conjunction with the aseptic process connections (e.g. clamp connection, VARINLINE ® , BioControl ® ) enables a dead-space free connection to the process.
The measuring instrument finds applications, for example, as an independent pressure indication, needing no auxiliary power, on portable tanks.

Diaphragm pressure gauge, flush, model PG43SA-S
The PG43SA-S in hygienic design can be used for CIP (cleaning in place) and SIP (sterilisation in place) and in wash-down areas, and it can optionally be completely sterilised in an autoclave. The measuring instrument can thus be cleaned reliably and time-efficiently. At an easily accessible point on the top of the case, the zero point can be easily corrected.
Based on a third party verification, the model PG43SA-S corresponds to the 3-A Sanitary Standard.
The QR code on the dial allows instrument-specific information such as the serial number, the order number, certificates and other product data to be retrieved from the internet easily and in the long term.
