STS |
• For aggressive and conductive chemicals
• PVC or PVDF
• Up to 5 electrodes
• Custom manufacturing
• Fixed alarming level
Level control of electrically conductive and corrosive liquids:
- Metal finishing industry
- Control of presence or absence of liquid (leak detection, empty piping etc.)
- Pump automation (fill or drain) with ES 2001 relay
The STS level probe with a relay ES 2001, detects a level of a conductive liquid.
The longest electrode is used as the reference. The electrical contact occurs when the reference electrode and another electrode are both in contact with the liquid. Then, the current in detection loop provoques through the relay ES2001, an amplified ON/OFF signal (see data-sheet 530-01).
Acid resistant materials:
With Hastelloy G30 electrode ends and PVC or PVDF stems, the STS probes are useful for level control of most acids.
Other electrode ends such as Tantalum, other stem materials (PTFE or PPH), are available on request.
