Seek help regarding the reverse connection of the 3051 differential pressure transmitter
Thread Content
A 3051c differential pressure transmitter was used on site; it was correctly connected with the high-pressure side using a capillary connection and the low-pressure side using a pressure guide tube connection. However, it was installed in reverse on site and cannot be adjusted. Is it possible to modify the settings of the transmitter? Please help, thank you!
The high-pressure side is connected via capillaries, while the low-pressure side is connected using pressure guide tubes. Wow! I was not aware of such differences in connections; we have always used pressure transfer pipes for connections and have never encountered any problems. Is there such a requirement?
It cannot be modified; it will be turned off along with the valve, and the transmitter can be reversed
It’s really hard to change that. You can ask the transmitter manufacturer to see if it’s possible to disassemble the transmitter and swap the high- and low-voltage wires inside.
It cannot be changed; the medium on the side where pressure is taken using a capillary should be different from that on the side where pressure is taken directly, and the valve also needs to be modified accordingly. Directly changing the positive and negative pressure chambers of the transmitter will cause problems in operation
This cannot be changed; those with capillaries are used. It’s best to turn off the valve and reinstall the pipeline system. The differential pressure transmitter of Model 1 can be adjusted by switching the high and low pressure terminals (the manufacturer’s password is required)
I’ve never seen such a level gauge! If it weren’t for single flange or double flange! !
The poster is referring to the 3051C differential pressure transmitter.
We have used this type of differential pressure transmitter; first, you need to determine the designer’s intent. If it is installed in the wrong way, there will definitely be problems, so change it!
