Model P53

SKU: P53

Capacitance Probe, Pressurized Vessel Insertion/Removal

The Delta Controls Model P53 Capacitance Probe is intended for applications where it would be impractical, or impossible, to depressurize or drain the process system for inspection and testing of the probe instrument. Such processes include oil refineries, gas cycle plants, large storage tanks, and toxic materials

The gland body is effectively elongated by the addition of a polished, seamless tube coaxially mounted over part of the sensing probe. A second sealing gland with PTFE seals is installed on the outside of the tube. A block valve on the vessel shuts off the tank liquid. The second gland is screwed into the block valve and tightened to prevent leaks. The valve is then opened and the P53 is pushed in through the valve until the active portion of the sensing rod is inside the vessel. A mechanical clamp locks the probe in position until a need to remove it occurs. The gland follower seal design has been reliably used for more than 30 years. The PTFE insulation jacket is a welded heavy extrusion and not a thin coating or merely glued in place

Features

  • Inspect, test, or service without shutting down or depressurizing the process
  • Remove or insert 'up-from-the-bottom' or 'in-fromthe-side' sensor without draining a tank
  • Simple, direct inserted design useful for many common applications
  • PTFE insulation allows operation on conductive or nonconductive materials
  • High pressure PTFE seal is reliable, and essentially corrosion proof
  • Open design is easy to clean and resists material collection and deposition
  • Easily installed in any orientation: vertically down or up, horizontal, or at an angle
