What is the detector head enclosed in?

• A. Plastic housing
• B. Aluminum shell
• C. Stainless Steel Housing
• D. Fiberglass case

Answer: (C)

The detector head is enclosed in a stainless steel housing to protect the sensor in harsh environments. Stainless steel offers strong mechanical protection, excellent corrosion resistance, and durability against impact and vibration, which is crucial when dealing with gases like H2S and various refrigerants. This housing helps keep contaminants out, maintains calibration by preserving a stable internal environment, and stands up to high temperatures and chemical exposure. Other materials like plastic, aluminum, or fiberglass can be less durable, more prone to corrosion, or less able to seal effectively in demanding industrial conditions.
