Technical Characteristics and Process Versatility
-
Active Build-up Compensation: The FTI51 uses a guard electrode to compensate for the electrical influence of material adhering to the probe. This ensures the device only triggers a “full” signal when the actual liquid level reaches the sensor, even if the probe is covered in thick sludge or paste.
-
Multi-Functional Detection: This sensor is highly versatile. It can be used for traditional high/low alarms, foam detection in conductive liquids, or identifying the interface layer between two different liquids (e.g., oil and water).
-
Integrated Pump Control: The FTI51 can be configured for two-point control (e.g., “Pump On” at the tip and “Pump Off” at a higher point on the probe) using only a single process connection, simplifying tank design.
-
Durable in Extremes: With a temperature range spanning from -80 °C to +200 °C and pressure resistance up to 100 bar, the FTI51 handles everything from cryogenic storage to high-pressure chemical reactors.
-
Fast and Simple Commissioning: Calibration is performed at the press of a button, significantly reducing setup time. Additionally, the electronics can be replaced without the need for a total recalibration of the measuring point.
-
High Safety Standards: Certified for SIL2 environments and featuring two-stage overvoltage protection, the FTI51 is built for critical infrastructure and safety-related applications.

Aplikasi Utama
-
Viscous and Sticky Media: Reliable switching in honey, chocolate, syrups, paints, and heavy oils that traditionally cause false alarms.
-
Interface Detection: Monitoring the boundary between two liquids of different dielectric constants in separation tanks.
-
Conductive Foam Detection: Detecting the top of foam layers in fermentation vessels or mixing tanks to prevent overflows.
-
Pump Dry-Run Prevention: Using the short reaction time to protect expensive pumps from running empty in process lines.
-
Chemical and Petrochemical: Reliable point level detection in aggressive acids or high-pressure hydrocarbons where safety certifications like WHG or SIL are required.
