Using differential capacitance as detecting principle to constitute capacitance type differential pressure transmitter, inputting pressure is 01.2kPa to 010MPa, etc.

Service medium: liquid, gas and vapor.
Overpressure limit: impose 0 (absolute pressure) 6MPa pressure on either side of the transmitter.

Temperature transmitter is to amplify the electrical signals from the sensor, to correct and depending on the model galvanically insulate them. The conditioned signal can then easily be transmitted over long distances to the in-/output sections of a process control system or controller. Since the electrical signal from the thermocouple or resistance thermometer is relatively strong, signal amplification in close proximity to the sensors is not required.

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.

Pressure transmitters, a sub-group of pressure transducers, feature additional reset and calibration options. With some sensor types it is possible, for example, to re-set the measuring span over large ranges. This calibration option is usually referred to by such terms as scale down, span reset or turn down. For instance, a transmitter with a measuring range of 0 to 400 psi and a range reset 1/10 can be calibrate to a measuring range of 0 - 40 psi while still giving a full output signal (4 - 20 mA, for example).
