| Abstract: | The pneumatic bridge sensor of the measuring system for separating sulfur from flue gas and dust is studied.In the case dynamic change of consistency of the flue gas contained sulfide and dust,the resistance variation of the pneumatic bridge arm is calculated.This thesis presents equilibrium condition for pneumatic bridge and gives out the signals while pneumatic bridge is out of balance.The paper also discusses how to apply working principle of the pneumatic bridge to the manufacturing of measurers units and bear a relation to temperature sensor.At last,the application of separating sulfur and collecting dust in industry stove is introduced. |
