4100-OWS Full Display Oil Thickness Monitor

Overview

The 4100-OWS Oil Water Separator Monitor provides continuous interface monitoring of static level oil/water separators. This unique oil level system provides complete flexibility for monitoring oil water separators in one complete package.

The 4100-OWS sensing probe monitors the capacitance field between the probe and the concentric shield. As the oil accumulates and displaces the water, the probe capacitance changes. This interface signal is used to provide outputs, displays and relay control.

Optional Interfaces

Analog Output 4-20 mA non-isolated
Communication RS-485 Modbus
