BLCSA series of single-point level probes (conductivity cell electrodes) is designed for usage in combination with conductivity level controllers/indicators. The active body of the electrode is made of (PTFE insulated) stainless steel allowing usage in food, pharmaceutical, and chemical industries. The electrodes of these probes have simple design and low cost. BLCSA sensors can be mounted on various vessels: metal or nonmetal, open-surface, closed, or pressurized. Different designs are available for solving various level measurement problems: protection against condensation and dripping, protection of leads from excessive moisture, usage in deep wells, etc.
