Device and equipment are two terms commonly used in engineering technology. The difference between them lies in the scope of use and function.
Device usually refers to a collection of equipment used to complete a specific process or system, including mechanical, electrical, instrumentation and other devices, and usually includes a system composed of multiple equipment and components. Devices are usually used in industrial production and chemical processes, such as oil refining devices, chemical plants, pharmaceutical plants, etc. Devices usually have complex process flows and control systems that require system integration, debugging, and operation.
Equipment refers to a single mechanical or electrical component used to complete a specific function, such as a generator, air conditioner, pump, etc. Equipment is commonly used in various industrial and civil fields, such as energy, transportation, construction, medical, etc. Equipment often has a single function and can be operated and maintained independently.
To sum up, the difference between devices and equipment lies in their different scope of use and functions. A device is a collection of equipment used to complete a specific process or system, usually including multiple devices and components, while an equipment is a single mechanical or electrical component used to complete a specific function, usually with a single function.
