The semiconductor industry utilizes a wide variety of liquids and chemistries. These liquids can be highly conductive acids, bases, and deionized water. Balluff's unsurpassed industry leading capacitive technology reliably detects these liquids when present and accurately turns off when absent. Offering a patented hybrid capacitive technology, these liquids can be detected through nonmetallic walls up to 10 mm thick. In addition, they are not affected by moisture, foaming, filming and material buildup.
