Summary

The pressure gauge operates by measuring the pressure of fluid in a system, with its internal structure involving a thin-walled, c-shaped metal tube called a Wave lamp tube. This tube deforms when pressure is applied, and the deformation is proportional to the pressure. One end of the tube is fixed while the other is connected to a micro gear set, which translates the deformation into the movement of the pointer. As pressure decreases, the tube returns to its original position, making the pointer move back, offering an insightful look into how pressure gauges function.

Q & A

What is the primary function of a pressure gauge?

The primary function of a pressure gauge is to measure the pressure of the fluid within a system by indicating the pressure level on its pointer.

How is the pressure gauge typically connected to the system?

The pressure gauge is typically connected to the fluid pipeline via a threaded socket, which allows it to measure the pressure of the fluid.

What is the pressure sensing element in a pressure gauge?

The pressure sensing element, also known as The Wave Lamp Tube, is a C-shaped, thin-walled metal tube with an elliptical cross-section.

How does the pressure sensing element work?

The pressure sensing element works by relying on elastic deformation when pressure is applied. The deformation of the tube is directly proportional to the applied pressure.

What happens when pressure is applied to the Wave Lamp Tube?

When pressure is applied to the Wave Lamp Tube, it deforms, and this deformation is used to indicate the pressure level by moving the pointer.

What is the function of the micro gear set in a pressure gauge?

The micro gear set is connected to the other end of the Wave Lamp Tube, and its function is to translate the deformation of the tube into rotational motion that drives the pointer of the gauge.

How does the pointer of the pressure gauge move?

The pointer moves as the micro gear set rotates, which happens due to the deformation of the Wave Lamp Tube when pressure is applied.

What happens to the pointer when the pressure decreases?

When the pressure decreases, the deformation in the Wave Lamp Tube is reduced, causing the tube to return to its original position, which in turn makes the pointer rotate back.

What role does the base play in the design of a pressure gauge?

The base holds one end of the Wave Lamp Tube firmly in place, providing stability and anchoring the tube during pressure fluctuations.

Who is credited with inventing the pressure gauge?

The script cuts off before providing the full information, but it refers to an inventor without giving a name.
