Which device is used to measure the pressure of steam within a boiler?

The device specifically designed to measure the pressure of steam within a boiler is the pressure gauge. Pressure gauges are commonly used in various industrial applications, including boiler systems, to provide real-time readings of steam pressure. They help operators monitor the pressure levels to ensure safe and efficient operation.

A pressure gauge typically consists of a dial and a sensing element, such as a Bourdon tube or a diaphragm, which responds to changes in pressure. This response causes the dial to move, giving a visual indication of the pressure levels. Properly functioning pressure gauges are critical for preventing potential overheating or pressure failures within the boiler system, making their use essential in maintaining safety and performance standards.

While a manometer is also a device used to measure pressure, it is primarily utilized for measuring smaller pressures or differences in pressure, often in laboratory settings rather than in high-pressure boiler environments. Thermometers are designed to measure temperature, and flow meters measure the flow rate of liquids or gases, making them unsuitable for measuring steam pressure directly.
