Definition of diaphragm pressure transducer
Thread Content
May I ask: Where does the definition of diaphragm pressure transmitters come from? I searched through a lot of information but couldn’t find a precise definition. I know that the flange diaphragm type pressure transmitter is a diaphragm type pressure transmitter. I mainly want to figure out whether a pressure transmitter with a threaded connection is a diaphragm-type pressure transmitter For example, Chuanyi’s PDS803 series.
Diaphragm pressure transmitters are transmitters that utilize a diaphragm; they are mainly suitable for viscous or slurry-like media as well as highly corrosive liquids. The connection method used does not matter – whether threaded or flanged connections are employed depends on the process requirements and operating conditions.
Thank you for your reply. Do you have models of diaphragm pressure transmitters with threaded connections? It would be great to have some samples; I’d like to learn from them.

No, you can ask the manufacturer for it
According to the Chuanyi PDS803 manual, the material used for the liquid-contacting part is a diaphragm; the 803 model is indeed a diaphragm-type pressure transducer with threaded connections
It is essentially a regular flanged diaphragm; meanwhile, the supplier is required to provide the lower flange as well, to convert it into a threaded connection
I took a look at the samples of Chuanyi PDS; the 843 differential pressure transmitter also has parameters related to the isolation diaphragm. In that case, most pressure transmitters available on the market these days are diaphragm-type, right?
For process connections with a diameter of DN50, we generally choose flanged diaphragm pressure gauges; for those with a diameter of DN10, we opt for pressure gauges with threaded connections.
