What is one way to classify pressure controllers in a boiler setting?

In a boiler setting, pressure controllers can be effectively classified by pressure levels, which distinguishes them as high or low pressure controllers. This classification is significant because it directly relates to the operational parameters and safety considerations of the boiler system. High-pressure controllers are designed to regulate systems that operate under elevated pressure conditions, while low-pressure controllers manage systems operating under lower pressure settings. Understanding this distinction is crucial for ensuring the appropriate controller is used for specific applications, helping to maintain safety and efficiency in boiler operations. Additionally, pressure ranges determine the types of materials and technologies used in the construction of the controllers, influencing their operational capabilities and reliability.
