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 2-1/2″ or 4″ – Lower and Back Mount Process Connection 1-1/2″ to 4″ Tri-Clamp® (‘3A’ third party compliant) Pressure Range Vacuum and 0 to 15 psi up to 0 to 1000 psi, includes compound ranges (maximum working pressure is limited by installation clamp rating).
