Absolutely. Load cell signals are typically very small (millivolts), making them susceptible to radio frequency interference (RFI). Cell phones, two-way radios, and wireless equipment can induce electrical noise in load cell cables, especially if the cables aren't properly shielded. The problem is worse with longer cable runs and improper grounding. High-quality installations use twisted-pair shielded cables with proper grounding techniques. Some facilities require radio-silent zones around precision weighing equipment.
