MBS1250-063G1856 pressure transmitter

  The main function of the pressure transmitter is to transmit the pressure signal to the electronic equipment, and then display the pressure on the computer. The magnitude of the current has a linear relationship, generally a proportional relationship. Therefore, the voltage or current output by the transmitter increases as the pressure increases, thereby obtaining a relationship between pressure and voltage or current. The two pressures of the measured medium of the pressure transmitter are passed into the high and low pressure chambers , The pressure of the low pressure chamber adopts atmospheric pressure or vacuum, which acts on the isolation diaphragm on both sides of the delta element (ie, the sensitive element), and is transmitted to both sides of the measuring diaphragm through the isolation diaphragm and the filling liquid in the element.
The pressure transmitter is composed of a measuring diaphragm and electrodes on both sides of the insulating sheet to form a capacitor. When the pressure on both sides is inconsistent, the measuring diaphragm is displaced, and its displacement is proportional to the pressure difference, so the capacitances on both sides are not equal, through the oscillation and demodulation links.
