Question 26General Subjects - QMED
70% to passWhich of the following direct reading pressure gauges is capable of measuring two pressures and displaying the difference between the two?
ASimplex gauge
BCompound gauge
CDifferential pressure gauge
DDuplex gauge
AI Explanation
The correct answer is C) Differential pressure gauge. A differential pressure gauge is capable of measuring two pressures and displaying the difference between them. This type of gauge is commonly used to measure the pressure drop across filters, orifices, or other devices where the difference between two pressures is of interest. The other options are incorrect because: A) A simplex gauge only measures a single pressure, B) A compound gauge measures both vacuum and pressure but does not display the difference, and D) A duplex gauge measures and displays two separate pressures but does not calculate the difference between them.
