The diaphragm pressure gauge from WIKA has been designed for pressure measurement in hygienic processes such as those in sanitary applications. Due to the design according to the diaphragm gauge principle it works with a dry measuring cell. That means, if the diaphragm should leak, no system fill fluid escapes into the process. Thus the model PG43SA pressure gauge increases process safety.
In addition to this, its design with a welded, flush diaphragm and surface roughnesses of ≤ 0.38 µm ensures very good cleanability. No deposits are left on the process connection, which could be optionally be electro polished. The entire measuring instrument can be steam-sterilised (autoclaved) at 134°C and is suitable for SIP/CIP processes.
By integrating the centre-back-mount process connection into the case a compact, robust and hygienic design of the pressure gauge is enabled. The instrument, available in nominal sizes of 40 and 63, is thus ideally suited for space-saving installation in mobile vessels for pharmaceuticals, their harsh operating conditions, cleaning from outside and the complete autoclaving in a built in situation.
