Electrode line bushings


Ambient temperature

-25 °C to max. +150 °C
depending on the core wire used


In submersible sewage pumps, motor and pump assembly are often separated by an oil chamber sealed with mechanical seals.

To prevent motor malfunctions or breakdowns it is absolutely necessary to detect possible leakages of the shaft seals and to carry out maintenance works in due time. Our BARTEC electrodes help you solve this problem most cost effectively.

The electrode essientially consists of a threaded metal sleeve and a metal sensor rod forming one block by means of a creepage-proof insulation material. An appropriate evaluation unit indicates any existing leak or due maintenance in good time.

Depending on type and application, BARTEC electrodes can be used for temperatures from -25 °C to +150 °C. They can also be used under conditions that deviate from the following basic technical data.
