Differences between thermal instruments and chemical process instruments

What is the most fundamental difference between thermal instruments and chemical process instruments?
Thermal instruments have a broader range than chemical process instruments; when thermal instruments are used in the chemical industry, they are called chemical process instruments.

There is not much difference; thermal power plants and heating systems use what are known as thermal instrumentation, while the oil and chemical industries use what are called chemical instrumentation. If the parameters being measured are the same, then the same type of instruments is used, and it would be best to refer to them collectively as automation instruments.
There is no difference; it’s just a different name.
Thermal instruments are generally used in the field of \"thermodynamics\"; they mainly refer to types of instruments that are used for measuring various parameters related to thermal engineering processes such as temperature, pressure, flow rate, and level. It generally does not include chemical analysis instruments, environmental measurement instruments, HVAC engineering instruments, etc. Thermal instruments are defined by their intended users, while chemical process instruments are classified by industry. But the overlapping categories between the two are quite large.
I learned it; I thought that thermal instruments were simply devices used for measuring heat……
There are significant differences between thermal instruments and chemical process instruments. Thermal instruments generally do not involve hazardous chemicals, while most chemical process instruments do. The application scenarios, types, and standard specifications for these instruments vary as well.
It’s easy to understand – that device is called a composition analyzer; it sounds much more sophisticated now, doesn’t it?
Haha, it depends on who’s looking at it. It’s the exact same thing – why distinguish between them? It’s simply called an automated instrument. The power plant and boiler industries refer to it as thermal instrumentation, while those working in the chemical industry call it chemical instrumentation. Whatever, they’re all used for automatic control – what’s the difference? However, in terms of standards, I feel that the industry standards in the chemical sector are relatively high. Take the pressure transfer tubes used in pressure regulation systems as an example: in the petrochemical industry, compression fittings and TUBE connections are commonly used, whereas in desulfurization and denitrification processes, welded union fittings with a diameter of φ14 are typically utilized.
Whether in the chemical industry or thermal engineering, instrument technicians have no status nor prospects; they’re a pair of unfortunate souls
