Pressure Transmitter Working Principle:

When we apply pressure to the Pressure Transmitter, then the applied pressure acts as a force on the diaphragm inside the pressure transmitter. Then the diaphragm either expands or compress depends on the applied pressure.

 

Diaphragm expand or compress basis on positive or negative pressure. The resistors are mounted on top of the diaphragm. So when the diaphragm expands or compress, the resistance value changes. These resistors are connected in a standard Wheatstone bridge. The change in resistance is measured using a Wheatstone bridge. The bridge output is proportional to applied pressure.

 

Note: In Some types of pressure transmitters manufactures can use capacitance, inductance, conductivity, piezo electric crystals etc in place of resistors. So depending on the applied pressure the diaphragm expands or compress, then respective sensor parameter like resistance, capacitance, inductance, piezo electric crystal etc.. will change and it is proportional to the pressure.

Finally this is all I could do in this tutorial and I hope it is simple enough to understand for newbies too.

If you’re facing any kind of problem or need any help regarding understanding of Pressure Transmitters then just leave your message in the comments or shoot me an email. Your feedback is much appreciated.

 

I’ll definitely get back to support you. Support me by sharing this post and socializing with me. 🙂

We are using Pressure Transmitter (Yokogawa Transmitter). Range from 5 bar to 100 bar.
It was located in Compressor discharge line (30″ Line).
Pressure Transmitter Operation Range up to 72 Barg. It is communicating via Profibus with Siemens PCS7 System.
When Compressor running that pressure transmitter giving spike of more that 100 bar for 10 seconds. That over range is tripping system.

Do you have any idea. Problem in transmitter Or PCS7 system. Please advice..

check the intial current of the compressor. this high amount of pressure only displayed on 10 sec.plz check the compressor if u have any gauge in that line check the gauge pressure also

Dear Sir,
Thank You for Your kind effort & co-operation. I am expecting a suggestion from You. Say I am using a Differential Pressure Transmitter for measuring Pressure, Level Or Flow. Output of Differential Pressure Transmitter is 4-20 mA but I want to display it directly on Monitor not in the om of mA rather Pressure or Flow.. So have any configureable Display ? So that I can recognize it 4mA means certain pressure & 20 mA means another certain pressure & it will follow equation like y=mx +c. It will also record the Data of specified time (after 10 minutes interval it will record & send) & it will send it to another computer through internet.

when i blow off either high side or low pressure side of my transmitter for cleaning the pipe line due to mud water my remote water level indicator does not work as normal before.

Thanks a lot for your illustrations …
If I want to convert these signals that produced by sensor (4-20ma) to Ethernet signal to transmit it to another location by antenna ,so what I need or work to do that …
