Model P22

SKU: P22

RF Admittance Probe, Large Tubular Ground for Entrained Solids

The Delta Controls Model P22 probe also has high intrinsic gain. It is equipped with a wrap around concentric ground reference sheath. It has high inherent gain sensitivity and allows full scale calibration over just a few inches when the liquid is conductive. The ground sheath is large and provides an open bore. It is intended for use when the liquid is viscous or carries entrained solids. The open bore also allows fast speed of response and resists plugging. The ground sheath produces a linear output signal when used in a plastic tank, a horizontal cylinder or any tank with nonlinear sidewalls. The electronic module/probe combo can be calibrated outside the vessel, when required, for convenience or safety.

Features

  • High inherent gain sensitivity
  • Allows full scale calibration over a very small level change
  • Works on viscous liquids or those carrying entrained solids
  • Works on liquids with low dielectric constants
  • Insensitive to surface turbulence and splashing
  • Built in ground reference works on lined tanks or all plastic tanks
  • Produces linear output signal in an irregular tank
  • Calibration can be done outside the vessel
  • Strong. Resists flowing currents, waves, and vortices

Applications

The Delta Controls Model P22 probe is equipped with a wrap-around concentric tubular ground reference sheath. It has high inherent gain sensitivity and allows full scale calibration over just a few inches when the liquid is conductive. The ground sheath is large and provides an open bore. It is intended for use when the liquid is viscous or carries entrained solids. The open bore also allows fast speed of response and resists plugging. The tubular ground reference produces a linear output signal when in a horizontal cylinder or other tank with nonlinear sidewalls. The electronic module/probe combo can be calibrated outside the vessel, when required, for convenience or safety.

The Delta Controls Model P23 probe is for interface service, and is exactly the same as the P22, except that it has vertical slots milled into the tubular ground reference sheath. These slots are offset and overlapping so that the liquid is always free to flow in or out of the sheath. This is a necessity when being used for interface service. The interface transition zone must not be kept from the sensing probe by a solid tube wall.
