I have a question for all of you experts: there is a doubt regarding the sensor of the Hangyang air separation transmitter
Thread Content
I have a question for the experts here: According to SH/T 3198-2018, section 5.3.2, inert media such as fluorinated oils are to be used in pressure (differential pressure) transmitters for the automation systems of petrochemical air separation units. I would like to ask: In the air separation units produced by Hangyang Oxygen, for the transmitters used in air compressors and nitrogen compressors – whose measurement media are air and nitrogen respectively – do these transmitters, which are not located in the cryogenic section, also have to comply with this requirement? Thank you so much!
You still need to ask the department responsible for regulating you; their decision is final. Actually, it’s all the same thing, right? For reference.
