Pressure Transmitter Animation

Pressure Transmitter Animation

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.
