Absolute Pressure Transmitter

Normally, imitate signal with digital signal need go through A/D device, Most of capacitor smart transmitter adopts the electric circuit of signal .Change capacitor signal to imitate signal, to get the digital signal through high precision A/D electric circuit's design normally it's complex, it's easily been disturb by noise .SST transmitter embed the board of line on the sensor ,signal circuit and sensor capacitor ,constitute the electric circuit of vibration .and also sending out the frequency signal. Because of separately unit may test directly to signal of frequency ,Thus get the digital signal directly ,So eliminated the A/D link ,also convert to the better way can be more simple reliable and the ability of interference rejection is strong.
