Technical Characteristics and Multi-Functional Utility
-
Multi-Point Detection: A single FTW31 probe can house up to five rods of varying lengths. This allows for complex control tasks—such as high-high alarm, high alarm, pump start, pump stop, and low alarm—all through a single mounting hole, significantly reducing installation costs.
-
No Calibration Required: The device is designed for simplicity. It comes with a standard setting that covers the most common conductive liquids, meaning it works immediately upon installation without the need for time-consuming commissioning or specialized tools.
-
Maintenance-Free Operation: Because the probe has no moving parts, it is not subject to mechanical wear or jamming. This ensures a long service life and high reliability even in applications where traditional float switches might fail due to debris or mechanical fatigue.
-
Flexible Rod Lengths: Rods can be ordered in lengths ranging from 0.1m to 4m. Depending on the application, rods can also be shortened on-site to perfectly match the required switching levels of the tank.
-
Safety and Certification: The FTW31 is certified for overfill prevention and leakage detection according to WHG (German Water Resources Act) and is available with international explosion protection certificates for hazardous areas.

Ứng dụng chính
-
Pump Control (Two-Point): Automatically starting and stopping a pump based on high and low level thresholds to prevent tank overflow or dry running.
-
Multi-Level Alarms: Providing a sequence of alerts (e.g., 20%, 50%, 80%, 95% fill level) in storage tanks for water, acids, or alkalis.
-
Overfill Prevention: Acting as a dedicated safety switch to shut down inflow when a critical maximum level is reached.
-
Leakage Detection: Installed in a collection sump to detect the presence of leaked conductive fluids.
-
Utility Monitoring: Level detection in utilities such as cooling water systems, condensate return tanks, and wastewater sumps.
