Reliable interface monitoring for alarm between two liquids
The sensing probe continuously monitors the liquid in a vessel and will alarm when the interface of a different dielectric liquid crosses the active probe. Typical applications include oil/water interface in pipes and separators, water accumulation in fuel tank bottoms, and product phase changes in process piping streams.
The 2852-IFA sensing probe monitors the capacitance field around the probe.
The probe is calibrated to one of the liquids. As the interface of the second product crosses over the probe, the probe capacitance changes. This change is used to activate the relays for alarm and control.
