Model P68 • Capacitance Probe, Sanitary Service, Metal Ion Free Service, Parallel Ground Features Virgin polypropylene or natural PVDF comes into contact with the process fluids Thick plastic jacketing is welded in place No cracks, joints, or crevices to collect contaminants Suitable for fluids used in silicon chip and electronics manufacturing Use in industrial processes which are extremely corrosive such as hydrofluoric acid plants, pickling lines, and plating solutions Plastic surfaces are flame smoothed for the best available surface Description The Delta Controls Model P68 Capacitance Probe has all plastic wetted parts. It is designed for use in processes and storage tanks where the possibility of contamination is prohibited. Process examples include etchants, high purity plating solutions, and ferric chloride. The P68 is also commonly used in industrial process systems which are extremely corrosive. Kynar® is highly inert and unaffected by almost all strong acids and bases below a temperature of 275 °F (135 °C). Applications include hydrofloric acid level, refinery hydroformers, bromine condensors, chlorine generation cells, and radioactive wastes. The P68 is a heavy-duty rugged sensing probe with jacketed ground reference rod and provides high reliability in difficult applications.
