Local differential pressure display
Thread Content
The process pipeline for the equipment has a diameter of DN80; the pipeline pressure is -1 KPa, and the pressure difference to be measured is 1 KPa. Local display is used – which type of differential pressure display would be appropriate in this case?
Differential pressure transmitter, or differential pressure gauge
Micro-differential pressure transmitters can be used for ranges not exceeding 1 KPA, while ordinary differential pressure transmitters can be used for higher ranges
You can choose an EJA differential pressure transmitter, or ones from Rosemount or Siemens will also work
From a cost-saving perspective, U-tube transmitters are sufficient for on-site use; a slightly better option is an on-site differential pressure gauge. For ease of use and intuitiveness, differential pressure remote transmitters are generally used, but they are costly.
I’ve seen a header that can rotate for the first time; it’s quite useful
