What could cause a pressure gauge to provide inaccurate readings?

• A. Routine maintenance
• B. Engineered installation
• C. Damage, corrosion, or incorrect installation
• D. Regular calibration checks

Answer: (C)

A pressure gauge can provide inaccurate readings primarily due to damage, corrosion, or incorrect installation. Damage to the gauge, such as dents or breaks, can interfere with its ability to measure pressure accurately. Corrosion can affect the internal mechanisms, leading to the gauge giving false readings. Additionally, if the gauge is improperly installed—such as being mounted at an incorrect angle or in a location that exposes it to excessive vibrations or heat—it may not function as intended, leading to incorrect pressure readings. While routine maintenance, engineered installation, and regular calibration checks are important for ensuring that a gauge operates accurately, they do not directly cause inaccuracies. Instead, these practices aim to prevent issues related to damage or improper installation. Thus, focusing on the integrity and correct setup of the gauge is crucial for reliable pressure measurement.
