The sensitivity of the pressure transmitter refers to the displacement rate relative to the measured change, and the sensitivity is a sign to measure the physical instrument, especially the electrical instrument pays attention to the improvement of the sensitivity of the instrument. Through the study of sensitivity, we can deepen our understanding of the structure and principle of the instrument.
In the linear range of the pressure transmitter, the higher the sensitivity of the pressure transmitter, the better, because only when the sensitivity is high, the value of the output signal corresponding to the measured change is relatively large, which is conducive to signal processing.
Regarding the sensitivity of the pressure transmitter, it should be noted that the sensitivity of the pressure transmitter is high, and the external noise that is not related to the measurement is also easy to mix, and it will also be amplified by the amplification system, which will affect the measurement accuracy. Therefore, it is required that the pressure transmitter itself should have a high signal-to-noise ratio to minimize the introduction of interference signals from the outside world.
Not only pressure transmitters, but all transmitters have certain requirements for sensitivity. And the sensitivity of the transmitter is directional. When the measured quantity is univector and its directionality is required to be high, a transmitter with low sensitivity in other directions should be selected; If the measurement is a multi-dimensional vector, the smaller the cross-sensitivity of the transmitter, the better.
