S 2M/PP JOLA bar electrode

Description

The JOLA S 2M/PP bar electrode is designed to signal the presence of an electrically conductive liquid caused, for example, by a burst pipe, via a connected relay.

Conductive bar electrodes must only be used in normally dry environments.

They can be installed from the top or the side. In both cases, ensure that the tips of the poles are only slightly above the ground to be controlled.

The conductive electrodes are equipped with two sensitive elements in the form of two electrode rods: 1 control electrode and 1 earth electrode. If two non-insulated surfaces of the electrode rod sensor come into contact with an electrically conductive liquid (e.g. water, acid, etc.), electrical contact is established and an alarm signal is emitted.

Before use, we recommend viewing the attached pdf documents under the Documentation tab.

S 2M/PP properties

Examples of use

• Use of a bar electrode to detect leakage of an electrically conductive liquid in the outer pipe of a two-pipe system
• Use of a bar electrode to detect leakage of an electrically conductive liquid at the lowest point (groove in the figure) of the collecting room
