What type of gauge should be used when a system's operating pressure will not exceed atmospheric pressure?

• A. Pressure gauge
• B. Manifold gauge
• C. Vacuum gauge
• D. Digital gauge

Answer: (C)

When a system's operating pressure will not exceed atmospheric pressure, a vacuum gauge is the appropriate choice. Vacuum gauges are designed to measure pressures that are below atmospheric levels, typically in a vacuum system. They provide accurate readings for operations that may be in the negative pressure range, which is essential for applications like refrigeration or certain industrial processes where precise vacuum levels are necessary. Using a vacuum gauge allows operators to monitor the performance and safety of systems that should not have any pressure above the surrounding atmospheric pressure. This is crucial for preventing overpressure scenarios that can lead to equipment failure or safety hazards. Other types of gauges, such as pressure gauges, are not suited for conditions where the pressure is expected to be below atmospheric, as they are designed to measure positive pressure levels. Therefore, in a situation where the pressure remains at or below atmospheric conditions, the vacuum gauge is indispensable.
