Model P52

SKU: P52

Capacitance Probe, Heavy Duty

The Delta Controls Model P52 Capacitance Probe is a heavy-duty, general purpose sensor for use in a variety of applications. The sensing rod is jacketed in thick, extruded and welded PTFE. There are no thin coatings or glued joints to fail. The P52 is intended for use in services with higher mechanical stress, such as agitated tanks, services requiring long unsupported sensing rods, mixers, etc.

The sensing rod sealing gland is extremely reliable, sealing in such process materials as steam, hydrogen cyanide, gasoline, chlorine, liquid oxygen, and wastewater. The gland follower seals reside inside the body of 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.
