How Steam Gauge Works

A steam gauge measures the amount of pressure or steam in a boiler or tank. It is used to identify the PSI level (pounds per square inch) that the steam is exhibiting in the tank. Created with components strong enough to handle pressure, it is designed to withstand pressure itself. These components include a thick glass covering that is usually made of bezel glass, metal container, and strong measuring device.

The Measuring Device

A steam gauge operates using two major components that are sealed in a tube. These are the vacuum and a small U-shaped rod made of a coiled wire. This rod is firmly connected to the vacuum inside the pressure gauge. When the pressure inside a tank increases, it affects the U shape of the tube, forcing the tube to pull outwards and expanding at both ends to make a straight line. It requires a lot of force to stretch the U rod do this and transform into a line, so if it needs to expand or straighten more, then more pressure is required.

Gauge Gears

The U tube was encased inside the back of the steam gauge often housed in steel. The pressure scale – a circular scale with notches along the edge – is placed on the front of the gauge. A thick glass sealed in a vacuum protects the pressure scale. The tube connected to a gear device moves the pointer around the scale when the tube expands. When there is more expansion or straightening of the tube, more movement across the gear is observed, and thus, produce a higher reading.

This is how a typical steam gauge works and is often used in many industrial applications. To know more information about this device, consult with the experts at Quest Tec Solutions by visiting its official website at http://questtecsolutions.com/steam-gauge.
