Bamo STS Resistive Level Probes

Bamo STS Resistive Level Probes 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.

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.
