Model P68

SKU: P68

Capacitance Probe, Sanitary Service, Metal Ion Free Service, Tubular Ground

The Delta Controls Model P68 sensing probe has all plastic wetted parts. It is designed for use in processes and storage tanks where the possibility of contamination cannot be allowed. Some process examples are silicon etchants, high purity plating solutions, and and ferric chloride. It is the same as the P66, except that it is equipped with a parallel encapsulated ground reference rod. The P68 can be used in plastic or glass tanks. It also can be used with level transmitters in horizontal cylindrical tanks.

Features

  • Only virgin Polypropylene or FDA approved natural PVDF comes into contact with the process fluids
  • Thick plastic jacketing is welded in place
  • No cracks, joints, or crevices to collect contaminants and biological agents
  • Built-in ground reference rod; does not require a metal tank wall
  • For industrial processes which are extremely corrosive such as hydrofluoric acid plants, bromine condensers, and plating solutions
  • Plastic surfaces are flame smoothed for the best available surface

Specifications

  • Working Pressure: -15 to +300 PSIG (-1 to +21 BAR)
  • Working Temperature: -40 to +300°F (-40 to +150°C), note that W.P. decreases as temperature increases.
  • Insertion Length: Up to 6 feet (1.8 meters)
  • Process Connection: 3"/150# R.F. ANSI flange; other types and sizes optional
  • Wetted Materials: PVDF or Polypropylene
  • Body and Support Parts: 316 Stainless Steel basic
  • Electronic Module: Compatible with all Delta Controls Models
  • Process Temperature Sensing: Optional -125 to +250°F (-80 to +122°C); 4-20 mADC output signal over a second 4-20 mA loop

Applications

The Delta Controls Model P68 sensing probe has all plastic wetted parts. It was designed for use in processes and storage tanks where the possibility of contamination cannot be allowed. Some process examples are etchants, high purity plating solutions, and ferric chloride.

The Delta Controls P68 also finds application in industrial process systems which are extremely corrosive. PVDF is very 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 condensers, chlorine generation cells, radioactive processes and wastes.
