Model P53 Capacitance Probe
Brand: Delta Controls CorporationThe Delta Controls Model P53 probe is very similar to the P51 general-purpose probe and is based on that design.
It 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 of the P53 is effectively made very long by the addition of a polished seamless tube mounted coaxial 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 over 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 the Delta Controls P53 without shutting down or depressurizing the process
- Remove or insert "up-from-the-bottom" or "in-from-the-side" sensors without draining the tank
- Simple direct inserted design is 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
