Model P51

SKU: P51

Capacitance Probe, Solid Rod, General Purpose Use

The Delta Controls Model P51 probe is designed as a general purpose sensor for use in many common applications. The sensing rod is jacketed in thick extruded and welded PTFE . There are no thin coatings or glued joints to fail. The sensing rod sealing gland is extremely reliable. Thousands have been used over the last 30 years, sealing in such process materials as steam, hydrogen cyanide, gasoline, chlorine, liquid oxygen, chocolate, and wastewater. The gland follower seals are inside the body, which has a solid exterior. There are no screwed together joints in the gland which can inadvertently be turned, causing leaks, environmental spills, and toxic discharges. The gland body may be made of exotic metal or industrial plastics for highly corrosive service.

Features

  • General purpose for most applications
  • Simple construction and easily installed
  • Small 3/4" MPT process connection size
  • PTFE insulation allows operation in conductive or nonconductive liquids at high temperatures
  • High pressure PTFE seal is reliable; up to 1500 PSIG (100 bar) working pressure @ 100°F (40°C)
  • Up to 450°F (230°C) process temperature
  • Clamped seal is very reliable, thousands have been in service for more than 30 years
  • Double gland seal available for lethal and toxic services
  • Open design resists material deposition and is easy to clean. Sanitary flanges are also available
  • Easy to install, vertically or horizontally; top down, bottom up, or in from the vessel side
  • Can be used in many slurry and entrained solids applications

Applications

The Delta Controls Model P51 and P52 probes are designed as a general purpose sensors for use in many common applications. The sensing rod is jacketed in thick extruded and welded PTFE . There are no thin coatings or glued joints to fail.

The sensing rod sealing gland is extremely reliable. Thousands have been installed over the last 30 years, sealing in such process materials as steam, hydrogen cyanide, gasoline, chlorine, liquid oxygen, chocolate, and wastewater. The gland follower seals are inside the body, which has a solid exterior. There are no screwed joints in the gland which can inadvertently be turned, causing leaks, environmental spills, or toxic discharges. The gland body may be made of exotic metal or industrial plastics for highly corrosive services.

The Delta Controls P52 probe has the same appearance as the P51 probe except that it has a larger gland, seal, and sensing probe. It is intended for use in services with higher mechanical stress, such as agitated tanks, services requiring long unsupported sensing rods, mixers, and the like.
