Which device on a regulator displays the pressure inside a cylinder?

• A. Torque wrench.
• B. Thickness gauge.
• C. Pressure gauge.
• D. Mechanical fingers.

Answer: (C)

The pressure gauge is the device that displays the pressure inside the cylinder. It’s a readout built into the regulator and connected to the cylinder so you can see the gas pressure at all times. This helps you know how much gas remains and when it’s time to replace the cylinder. Some regulators also have a second gauge for the regulator’s outlet pressure, but the one that shows the cylinder’s pressure is the pressure gauge. The other items aren’t used to read cylinder pressure: a torque wrench measures the tightness of fittings, a thickness gauge checks material thickness, and mechanical fingers are not standard indicators on regulators.
