🔍 Key Concepts

• Ground loops and how multiple ground connections can introduce noise in low-level analog signals • Why shielded cables are used for thermocouples and other low-level analog signals • The idea of single-point (one-end) grounding of the shield to prevent interference

💭 Think About

• Look at which drawings have the cable shield connected to ground at more than one point. How would that affect circulating currents in the shield? • For a very low-level signal like a thermocouple, do you want the shield carrying any current related to differences between two grounds? Why or why not? • Which end of the circuit (sensor end or instrument/computer end) is usually treated as the main reference point for signal processing and noise rejection?

✅ Before You Answer

• Identify the option(s) where the shield is grounded at both ends and think about whether that can cause a ground loop. • Check which illustration keeps the signal pair isolated while using the shield only as an electrostatic shield, not as a current-carrying conductor. • Confirm that the chosen option has only one shield-to-ground connection and that it is at the end that best controls noise for measurement electronics.
