EHW 1-4 JOLA hanging electrode

Description

The EHW 1-4 JOLA hanging electrode is designed to signal the presence of an electrically conductive liquid caused, for example, by a burst pipe, via a connected relay of the bar electrode.

Suspension conductive electrodes are designed to signal the presence of an electrically conductive fluid caused by, for example, burst pipes, via a connected conductive electrode relay.

Suspension conductive electrodes must only be used in normally dry environments. They must be installed in a hanging mode from above, so that the electrode rods are only slightly above the floor to be controlled.

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

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