SCHAFFER DIAPHRAGM GAUGE DMC CASE FLANGE CONNECTION The model P91/SE Schaffer Diaphragm gauges are manufactured with a special DMC (Dough Moulding Compound) safety case and are designed for use on slurries, viscous or corrosive fluids that would normally attack or block standard bourdon tubes. Implementing specialist materials for both the connection and diaphragm enable the Shaffer Diaphragm gauge to be configured for use on any gaseous or liquid media including suspended solids or powders. The direct drive from the diaphragm to the movement ensures a more positive indication of pressure than other models of tube gauges. Offering a full range of flanged connection sizes and materials, Schaffer Diaphragm gauges can operate at pressure ranges as low as 30 mBar with the option to permit units to withstand Case & Bezel DMC (Dough Moulding Compound) is glass-reinforced polyester with central partition and blow out back. It has extremely high impact strength, is self-extinguishing. Scale Ranges 0 to 30 mBar up to 25 bar Pressure / Compound ranges Equivalent units of pressure / vacuum available Single and dual scales are available Option: Custom scales for special applications, i.e. tank contents Units withstands overload pressure up to 125% of FSD See reverse for maximum overloads for different materials Pressure Connection All Connections have a Bobin Neck assembly except flanges 1.5" & 2" 900/1500RF & DN50, where this is not required Connection Material 316 Stainless Steel as standard Options: Carbon Steel, Monel, Titanium, Hastelloy, Tantalum Lining Options: PTFE, Halar, PDA Diaphragm Material 316 Stainless Steel as standard Options: Monel, Tantalum, Hastelloy, Silver or PTFE Protected Other materials to suit application are available Accuracy Class White Anodised Aluminium marked in black finish Dual scales, bands and sectors are also available Customisation with company Name & Logo Stainless steel coloured black Option: Micrometer adjustable pointer for Rangesa 350 mBar Stainless Steel Construction Laminated Safety Glass (Standard) Option: Acrylic Plastic Window Environmental Rating All instruments are individually calibrated and have an unique Serial Number printed on the dial.
