"Over 40 years of Arjay’s field proven HF capacitance experience has been applied to the 4100-OWS series monitors. This unique oil level system provides complete flexibility for monitoring oil water separators in one complete package.","• unique capacitance approach eliminates routine cleaning • no moving parts • control and interface panel mounts safely away from the process","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."
