Dry Bulb Parameter sensors must be hung with what material?

Dry Bulb Parameter sensors must be hung with what material?

• A. Non conducting material
• B. Conducting material
• C. Insulating material
• D. Metal chain

Answer: (A)

The main idea is to keep the sensor reading true to the surrounding air while maintaining safety. A non-conducting hanger prevents any electrical path to ground or through the sensor leads, which could introduce stray currents or shocks. It also minimizes heat transfer along the support, so the hanger itself won’t bias the ambient temperature reading. A conducting hanger, like a metal chain, could conduct electricity and alter the reading or pose a safety hazard. An insulating material might reduce some heat transfer, but non-conducting explicitly ensures there’s no electrical conduction path, which is why it’s the best choice.
