VEGA EL 4 Conductive probe - Manual (Page 11)

Fig. 4: Inflowing medium
The probe should protrude into the vessel to avoid buildup. For that
reason, avoid using high mounting bosses for screw-in fittings. This
applies particularly to use in adhesive products.
Make sure that the mechanical connection of the probe to the vessel is
electrically conductive to ensure sufficient grounding.
Use conductive seals, such as those made of copper or lead, etc.
Insulating measures, such as covering the thread with Teflon tape, can
interrupt the necessary electrical connection with metal vessels. For
this reason, ground the probe on the vessel or use a conductive seal
material.
