Technical Characteristics and Hygienic Superiority
-
Superior Build-up Compensation: The FTW33 is designed to “see through” heavy layers of sticky products like chocolate, honey, or yogurt. It accurately distinguishes between a true full-pipe condition and residual film on the sensor face, ensuring reliable switching.
-
Flush-Mounted Design: The sensor sits flush with the internal wall of the pipe or vessel. This not only prevents material from trapping around the probe but also allows for the pigging of pipes, which is essential for product recovery and thorough cleaning in food production.
-
Industry 4.0 Ready with IO-Link: Integrated IO-Link communication simplifies device configuration and allows for remote diagnostics. This digital interface makes it easy to integrate the sensor into any modern fieldbus architecture while reducing wiring complexity.
-
Robust CIP/SIP Capabilities: Built to withstand the harshest cleaning cycles, the FTW33 is rated for temperatures up to 150°C (302°F) for sterilization (SIP) and holds the highest protection class of IP 69.
-
No Individual Adjustment: For most standard applications, the device is “plug-and-play.” It automatically detects the medium without the need for manual sensitivity tuning for every new product batch.

Primary Applications
-
Food and Beverage Production: Level detection in mixing tanks for sauces, syrups, or dairy products where heavy coating occurs.
-
Pipe Monitoring: Detecting the presence or absence of liquid in process pipes to protect pumps from dry-running.
-
Foam Detection: Capable of detecting the presence of foam in food processing vessels, a critical factor for preventing overflow in fermentation or filling tasks.
-
Cleaning Systems (CIP): Reliable monitoring of cleaning agents and rinse water in return lines.
-
Space-Restricted Installations: The compact housing allows for mounting in tight manifolds or small vessels where traditional probes are too large.
