The device is used in conductive liquids (as of 10 μs/cm) for determining level limits.
Depending on the number of measuring points (up to 5 rods or ropes), measuring tasks such as overspill protection, dry running protection, two- point control of pumps or multiple point detection can be implemented for an existing process connection.
