Model P57

SKU: P57

Capacitance Probe, Parallel Ground Reference

The Delta Controls Model P57 probe is commonly used in tanks made of reinforced plastics, or metal tanks lined with rubber, glass, or plastic. Such tanks do not provide the ground reference plane required by an admittance instrument. The P57 has a ground rod, mounted parallel to the insulated sensing probe, which provides the required ground reference. A stability bar(s) stabilizes the sensing probe and ground rod position when the insertion length is long. The P57 is widely used on water treating chemicals, stored fuel oil, day tanks, oil/water interface, and processed food oils. The open design allows it to be used in many applications; even when solids are entrained in the liquid.

Features

  • Direct insertion, open construction
  • A rod parallel to the sensing probe provides a linear ground reference and increases sensitivity
  • PTFE sensing rod jacket allows operation in conductive or nonconductive liquids
  • High pressure PTFE seal is reliable. Thousands have been in service for over 30 years
  • Service working pressure to 1500 PSIG (100 BAR)
  • Service working temperature to 450°F (230°C)
  • Can be used to measure liquids with entrained solids in most applications
  • Works in highly corrosive applications
  • Available with sanitary flange
