EHW 1-4

• without cable break monitoring

• with electrode rods made of Hastelloy B

For signalling the presence of an electrically conductive liquid caused, for example by burst 
pipes.

If the two electrode rods of a suspension come into contact with an electrically conductive 
liquid (e.g. water, acid etc.), an electrical contact is made and an alarm signal given.

Available electrode rods:
- stainless steel 316 Ti
- titanium
- Hastelloy C
- Hastelloy B
- Monel
- tantalum

Mounting accessories:
Stuffing glands, stuffing glands with mounted connection box and flange with stuffing glands
on request

The suspension electrode is fitted with two separate electrodes in the form of two electrode 
rods: 1 control electrode and 1 earth electrode. As soon as a trace of a conductive liquid 
creates a conductive path between the two electrode rods, a control current flows from the 
corresponding electrode relay. The latter is then energised and a contact made.

The suspension electrode may only be connected to the Leckstar 101 electrode relay.

Max. length of connecting cable between suspension electrode and electrode relay: 1,000 m.
