ILT Food

Level Indicators ILT Food: Certified Level Control for Powders and Granules in Food Processing

The ILT Food Level Indicator is the food-grade evolution of the TOREX® rotary level
indicator. Designed for hoppers and silos, it provides a repeatable ON/OFF signal at
minimum and maximum levels.
Why ILT Food Makes the Difference
 Food-Certified: The EC 1935/2004 version with IP65 protection is engineered to
eliminate product build-up zones. Threaded connections comply with food-contact
requirements.
 Dust-Safe Operation: EX II 1/2D (ta/tb IIIC T100 °C) version available on request.
 Easy Integration: Relay interface for PLCs or alarms, with robust and reliable
ON/OFF logic.
How It Works in Practice
The rotating paddle detects product presence; torque reaction stops the motor and triggers
the relay. When the level drops, the system automatically restarts. The operation is binary,
stable, and easily diagnosable — ensuring dependable level control over time.
