Cost-effective level limit switches for multiple point detection in conductive liquids.

Applications Liquipoint T sensors are used in conductive liquids (as of 10µS/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-run protection, two-point control of pumps or multiple point detection can be implemented for an existing process connection.

Liquipoint T sensors feature a builtin electronic insert with either a transistor or relay output for 2 or 3 rod/rope probes. With no moving parts in the tank, they offer reliable operation and a long service life.

Specially designed for hygienic applications, the FTW33 meets all international hygiene requirements. It is particularly suited to applications where flush mounting is necessary and can be used in processes up to 100°C with no limits and in cleaning and sterilization processes to 150°C for 60 minutes. And, with build-up compensation, reliable switching is guaranteed time after time.
