Italian to English Tech/Engineering Mechanics / Mech Engineering

This is from a user manual for a chain conveyor.
It talks about a "sensore antingolfamento".

Other examples:

- "Sulla zona di scarico c'è un sensore che rileva l’eventuale ingolfamento del materiale e blocca la macchina evitando carichi eccessivi alla macchina stessa"

- "ingolfamento del trasportatore"

The only term I can find for "ingolfamento" is "flooding", thus "anti-flooding sensor", but I'm wondering if there isn't a better term in this context. I wouldn't like it to be confused with "flooding the engine" of a machine.

Thanks!
