9820 | 9830-OWS Oil / Water Separator Level Alarm Reliable interface monitoring of oil/water separators, sump pits and containments for pump control and alarm Over 30 years of Arjay’s field proven HF capacitance technology has been applied to the 9820/9830-OWS oil water separator alarms. The sensing probe continuously monitors for oil to control pumps, operate valves, or activate alarms.
9820 | 9830-OWS The 9820/9830-OWS sensing probe monitors the capacitance field around the active probe tip. As the volume of separated oil increases in the separator or is drawn down toward the probe tip, the probe capacitance changes. This change is used to activate the relay for alarm interface and control.

When the presence of oil displaces the water the level probe senses the decrease in capacitance and the control unit will indicate an alarm condition and change the state of it’s dry relay contacts.

INSTALLATION NOTE: If any damage to the instrument is found, please notify an Arjay Engineering representative as soon as possible prior to installation. Choose the mounting location in accordance with good instrument practice. Extremes of ambient temperature and vibration should be avoided. 2.

Alarm Time Delay This is set via the Alarm Delay switch. An alarm based on the Relay Action switch must be present for at least the time delay value for the relay to switch to the alarm state. There is no delay when switching off the alarm. The delay range is 0 – 20 seconds.
