Capacitance Probe, Pressurized Vessel Insertion/Removal

The Delta Controls Model P68 Capacitance Probe uses all plastic wetted parts and is intended for sanitary service. The probe 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® PVDF is highly inert and unaffected by almost all strong acids and bases below a temperature of 275 °F (135 °C). Applications include hydrofluoric 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.
