S 2 M/PVDF-Z10

• with integrated Z10 cable break monitoring unit

• with electrode rods made of stainless steel 316 Ti

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

If the two non-insulated electrode rod sensor surfaces of a rod electrode 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: 4 mm dia. made of:
- stainless steel 316 Ti
- titanium
- Hastelloy C
- Hastelloy B
- Monel
- tantalum
covered with shrinkdown tubing made of:
- polyolefine or
- PVDF or 
- PTFE

Lengths: as required (measured from nipple sealing surface)
Max. lengths: approx. 2500 mm; longer rods on request

On request: aluminium connection head, protection class IP 54

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

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