Arjay - Model 2852-OWI - Remote Mounted Oil/Water Interface Monitor

The 2852-OWI sensing probe monitors the capacitance field around the probe.

A calibration is performed against the an oil condition and a water condition. The active portion of the probe is fully submerged into the liquid and sized to your targeted range of interest. As the oil/water interface or emulsion crosses or envelopes the probe, the capacitance change is tracked and an output of 4-20 mA is provided.
