Question: 1 / 495

What is the maximum range for a 3 psi gauge with a 2-inch diameter?

Shall not exceed 3 psi

Shall not exceed 4 psi

Shall not exceed 5 psi

The maximum range for a 3 psi gauge with a 2-inch diameter is based on industry standards and the design specifications for pressure gauges. Typically, a pressure gauge is designed to measure pressures up to a certain maximum value which is often slightly above the intended measurement range to ensure accuracy and proper functioning.

In this context, a gauge rated for 3 psi would typically have a maximum capacity of 5 psi. This allows for pressure fluctuations and ensures that the gauge can accurately read pressures that might exceed the base measurement slightly without compromising its integrity or reliability. This additional range also provides a safety buffer, which is crucial in many pressure monitoring applications to avoid gauge failure or inaccuracies when pressures spike.

Thus, acknowledging the designed specifications for safety and accuracy, stating that the maximum range shall not exceed 5 psi is correct.
