Dial pressure gauge 91/CFN

diaphragmprocess

The model 91/FN Schaffer Diaphragm gauges are designed for use on slurries, viscous or corrosive fluids that would normally attack or block standard bourdon tube gauges. 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 a maximum pressure of 70 bar.
