What is the purpose of a pressure gauge snubber with a porous metal element?
A. To protect the gauge from damage due to vibration or pulsation
B. To increase the accuracy of the gauge reading
C. To reduce the effects of temperature changes on the gauge reading
D. To prevent contamination of the gauge with foreign substances
Answer:D

Explanation: A pressure gauge snubber with a porous metal element is designed to prevent the gauge from being contaminated with foreign substances that may be present in the process being measured. The porous metal element acts as a filter that allows the pressure to pass through but prevents any particles or contaminants from entering the gauge.
