Hygienic Diaphragm Seals HYGEIA ‘Quality Matters’ Introduction PCI’s HYGEIA range of hygienic diaphragm seals are manufactured to the highest possible standard in the United Kingdom. Designed for use in the food process and pharmaceutical industry. A diaphragm seal’s main purpose is to protect the pressure instrument from the process medium. Diaphragm seals are normally connected directly to the instrument but connection may be made by a capillary. The air space behind the diaphragm membrane and inside the instrument is filled with a fill fluid which acts as a hydraulic medium. When pressure is applied to the diaphragm membrane it is hydraulically transmitted to the instrument’s sensing element by the displaced fill fluid. This allows the instrument to measure the process pressure without making direct contact with the process. Special features • Flush welded diaphragm (free of dead space) • Low fill fluid capacity helps to prevent measurement errors caused by high of fluctuating temperatures • Diaphragm protected against rupture with backup convolution • Helium leak tested to ensure integrity of diaphragm • Suitable for CIP and SIP processes Nominal pressures See tables on page 2 and 3 Options for diaphragm seal • Diaphragm with surface roughness Ra <0.38 pm for high cleanability in CIP process • Other instrument connections on request • Other construction materials on request Available certification • 2.1 Certificate of conformity • 3.1 Material certificate • Others on request How to order diaphragm seal Please specify: model, diaphragm seal type, size, options, certificates Example: HYGEIA, Tri-clamp, 2”, 3.1 material certificate Diaphragm seal specifications Body Material: AISI 316L Nut Material: AISI 304 Wetted Part and Diaphragm Material: AISI 316L Specifications are subject to change without notice Web: www.pci-instruments.com | Email: sales@pci-instruments.com | Tel: +44 (0)170
