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

5 Nov 2025  |
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.
