Conductivity liquid level switches

Conductivity level switches from VEGA offer the simplest of solid-state level switching technologies. It gives a straightforward solution on basic applications such as level switching on water handling systems ideal in building management applications for example. VEGAKON also has a technical “twist” - utilising our admittance technology to allow some systems to be used as a hygienic level switch with a flush design which can be used in pipework with conductive, adhesive products, for example.

Whatever your requirement a VEGAKON conductivity level switch has an answer - just ask us for details.

VEGAKON conductivity level switches can be side or top mounted, electrodes come in stainless steel or high resistance Hastelloy and can be cut to length by the customer on site. Systems are generally unaffected by temperature and pressure. Some have flush hygienic electrodes and they use admittance technology to ignore adhesive build up or residue.

• On almost any conductive, free flowing liquids
• Special hygienic level switch versions for conductive adhesive products and for full/empty pipe detection
• Tank level control
• Pump and process protection

• Cost effective and reliable performance
• Ideal on simple applications
• Easy to set up
• No moving parts mean high long term reliability
• Admittance technology on flush mount systems (VEGAKON61/63)

Conductive electrodes detect the level when the electrode(s) is touched by the product. A low, adjustable resistance, alternating current flows between the “earth” or “ground” and the probe. This current is detected by the signal conditioning instrument or compact instrument and processed into a switching signal. The switch point is determined by the length and mounting position of the appropriate electrode. In conductive vessels, the vessel wall forms the ground electrode. In a plastic vessel case, the conductive electrode consists of one of the probes.
