It's a tiny capacitive level sensor that detects the presence of various liquids. It detects the presence of conductive and non-conductive liquids (water, water solution, cooling liquids, oil, and so on). The magnetic pen included with the product makes it simple to change the sensitivity.
It may be put directly on various containers and tanks due to its compactness and easy construction. S, PNP, and NAMUR output signals (for explosive zones)
High temperature performance and resistance to pressures up to 70 bar. M18, M20, G3/8" or 1/2-14 NPT threads are available for process connections.
