For newly purchased small units equipped with condition monitoring, what functional requirements should be specified in the instrumentation technical agreement?
Thread Content
I’ve just bought a new small unit. Is it expensive? Not really, but it’s not cheap either. I’m thinking that if it becomes possible in the future to add condition monitoring, what technical requirements should be met for the relevant instruments?
What kind of unit? What instruments are there now? If you yourself don’t know what your requirements are, then don’t impose demands on the manufacturer just to make things difficult for them~

Vibration displacement, rotational speed, temperature, and pressure – these depend on the requirements of the process and equipment fields; it’s best for the signals to be in the 4-20 mm range, as there are many signal amplifiers and transmitters available for vibration displacement. Also request the explosion protection rating and brand standards. For the process equipment category, add whatever is required; for the instrumentation category, simply specify the technical requirements for these monitoring points. Install an explosion-proof junction box on site to consolidate these signals.
