In the world of engineering and pressure measurement, the Bourdon pressure gauge stands as a fundamental and highly reliable device. This mechanical instrument has been an integral part of various industries for over a century, playing a crucial role in ensuring the safe and efficient operation of systems.
1. Introduction to Bourdon Pressure Gauge
The Bourdon gauge dates back to 1849 and was invented in France by Mr. Eugene Bourdon. Despite its rather unassuming appearance, it has become one of the most widely spread pressure measurement devices. It is designed to m
easue and display pressure in both gas and liquid state systems, making it extremely versatile.
The simplicity and reliability of the Bourdon gauge have contributed to its popularity. It provides operators with a clear visual indication of the pressure within a system, allowing for easy monitoring and control. Moreover, it is relatively cheap, which makes it accessible for a wide range of applications.
2. How Bourdon Pressure Gauges Work
The heart of the Bourdon gauge is the Bourdon tube. This tube is manufactured in a semi-circular C-shape or a coiled shape. One end of the tube is open to the atmosphere, while the other end is sealed closed.
When there is an increase in the system pressure within the tube, the tube expands and straightens. Although this change is small, it is magnified due to the shape of the tube. The change in the C-shape or coil radius is then transferred to the indicator needle. This movement of the needle allows personnel to visually view the pressure within the system, providing an accurate reading of the pressure.
3. Applications of Bourdon Pressure Gauges
The Bourdon gauge has been in existence for over 100 years in various forms and remains one of the most common pressure gauges available today. Its applications are numerous and span across different industries.
In the industrial sector, it is used in a wide range of gaseous and liquid state systems. This includes monitoring the pressure in pipelines, tanks, and vessels in industries such as manufacturing, chemical, and oil and gas. In power generation plants, it helps in ensuring the proper functioning of boilers and turbines by measuring the pressure of steam and other fluids.
In the automotive industry, Bourdon gauges can be found in applications such as measuring the pressure in braking systems and hydraulic systems. In the building services industry, they are used to monitor the pressure in heating, ventilation, and air conditioning (HVAC) systems, as well as in water supply systems.
4. Advantages and Considerations
One of the major advantages of the Bourdon gauge is its reliability and robustness. It can withstand harsh operating conditions and provide accurate pressure readings over a long period. However, it is important to note that any blockage of the piping leading to the open end of the Bourdon tube can render the gauge unreliable or even totally inoperable.
Repairing the gauge is rarely possible without specialist equipment. But given its relatively low cost, it can be easily held as a spare part, minimizing downtime in case of gauge failure.
