Selection issues for micro-pressure transmitters
Thread Content
In a normal operation of this project, the pressure inside the reactor is slightly positive, around 20–30 kPa; the maximum value is 50 kPa during nitrogen purging. Is it necessary to use a gauge pressure transmitter? Still a micro-pressure transmitter? What range should be chosen? Thank you
Is 20.30.50 still a slight positive pressure? It’s not small anymore
A differential pressure transmitter with a range of 100 kPa will suffice...
A differential pressure of 2 KPa or less is considered micro-differential pressure; for your case, a regular differential pressure will suffice: lol
A regular differential pressure gauge will do; there are many domestic options available. The main issue is instability, and for imported ones, you can turn to me
