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.
