Model P57

SKU: P57

Capacitance Probe, Parallel Ground

The Delta Controls Model P57 Capacitance Probe is commonly used in tanks made of reinforced plastics or metal tanks lined with rubber, glass, or plastic which do not contain the ground reference plane required by a RF admittance instrument. The P57 has a ground rod mounted parallel to the insulated sensing probe, which provides the required ground reference

The P57 stability bar(s) steadies the sensing probe and ground rod position when the insertion length is long. The probe 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
  • Rod parallel to sensing probe provides linear ground reference and increases sensitivity
  • PTFE sensing rod jacket allows operation in conductive or nonconductive liquids
  • Reliable high pressure PTFE seal
  • Can be used to measure liquids with entrained solids in most applications
  • Works in highly corrosive applications
