Problems with the transmitter process interface.
Thread Content
I would like to ask everyone: our factory’s pressure transmitters come with process interfaces that can be connected in different ways, including via an M20*1.5 connection. What are the differences between these two design options? What are their respective advantages and disadvantages?
Flanges are commonly used in situations where the medium is prone to clogging or sticking, while threaded ones are of the standard type
The M20*1.5 seal is sealed using a small PTFE gasket (we usually use 18*8*3 PTFE gaskets); wrapping something around it is of no use. The tapered thread of the NPT can be fitted with a collar. Flange pressure tapping is generally used for media that are viscous and prone to crystallization.
For the one with threads, they didn’t even install a valve assembly
@Moderator dennyshen2549 said that the flange connection has a high voltage tolerance.
Huai’an Sanchang Instruments: The main difference between threaded connections and flanged connections lies in whether the medium is corrosive; if it is corrosive, a flanged connection should be used. This is an answer found on Baidu.
The electrical interface can use M20*1.5 or NPT1/2 threads
For any measurement process, it depends on its process parameters. Take a look – does the pressure measured in that environment reach 100 MPa? It seems like you’re using your mouth to make the measurements
