Technical Characteristics and Material Versatility
-
Flexible Output Options: The FTS20 is available with two distinct electrical outputs:
-
Change-over contact: A universal AC/DC switch for standard industrial applications.
-
NAMUR signal: Specifically designed for use in hazardous areas (up to Zone 1) when connected to an isolating amplifier.
-
-
Media-Specific Materials: To ensure high safety and chemical compatibility, the float and cable can be ordered in various materials:
-
PP (Polypropylene) or PVC: For standard water and wastewater.
-
PUR (Polyurethane) or CSM (Chlorosulphonated Polyethylene): For oily or aggressive liquids.
-
-
Simple Installation: Its small diameter allows for easy mounting through a standard G 1 A tapped hole. The switching point is determined simply by the length of the cable and the point at which it is secured.
-
Robust Mechanical Principle: With no complex electronics in the sensor head, the FTS20 is highly resistant to interference and mechanical shocks, providing a long service life with minimal maintenance.

主な用途
-
Sewerage Treatment Plants: Level detection in open basins and sumps to manage pump cycles.
-
Overfill Prevention: A safety limit switch for storage tanks to prevent accidental spills.
-
Pump Dry-Run Protection: Ensuring pumps do not run when the liquid level falls below a critical minimum.
-
Oily and Aggressive Media: Reliable switching in industrial sumps containing lubricants or mild chemicals.
-
Small Vessels: Due to its compact design, it is suitable for smaller tanks where space for larger level sensors is limited.
