Direct Drainage Reviews



The 25mm diameter High Oil Probe is used primarily in grease separators and is designed to detect the presence of oil or water and will only cause an alarm when excessive oil is present.

The depth of oil allowed to accumulate inside a tank before an alarm is raised will be determined by the position of the probe below the static liquid level.

The 2 pieces of stainless steel act as conductors, when the probe is fully immersed in water, a circuit is formed between the conductors. When one or both of the conductors are out of water, i.e. in oil, the circuit is broken and a signal is returned to the separator alarm panel.


This probe is included as standard in Kingspan Klargester and Spell separator tanks, washdown units and cesspools.


We also supply the 38mm High Oil Conductivity Probe which is included as standard in the Complete IP65 Mains Separator Alarm with High Oil Probe
