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.

การใช้งานหลัก
-
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.
