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
- Hastelloy C
- Hastelloy B

Available connecting cable:
- PVC connecting cable or
- CM connecting cable or
- PTFE connecting cable

Version with electrode rods made of:
- stainless steel 316 Ti
- Hastelloy C or
- Hastelloy B and/or
with housing made of PVDF or PTFE on request.

Mounting accessories:
Stuffing glands,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 should be connected to electrode relay 
Leckstar 101/Ex  I (M1) / II (1) GD [EEx ia] I / IIC.

Max. cable length between electrode relay and electrode(s):
