Description
Design
All-welded construction in full compliance with ‘3A’ third party
standards and meets the most rigorous biopharmaceutical
industry specifications. This assembly has all the advantages
of the 23X.50 series mechanical gauge (ASME B40.100 & EN
837-1) and WIKA combines it with a superior designed sanitary
diaphragm seal. All external stainless steel surfaces are
electropolished and the wetted components have full material
identification and traceability. The diaphragm and its body
have matching convolution patterns to greatly reduce potential
diaphragm damage due to mishandling and to minimize
temperature effects.
Gauge Nominal Size
