The sensitivity of the instrument refers to the sensitivity of the instrument to the change of the measured parameters, and it can also be said to be the amplification of the output of the change of the measured parameters. Sensitivity can be expressed as Sensitivity (should be ε) = amount of change in response / amount of change being measured. It can be seen that sensitivity is actually the degree to which the instrument reflects the parameters being measured. We usually talk about high sensitivity, but simply put, it is a little change, and the instrument can reflect it correctly. For example: weighbridge scales and scales. The weighbridge says that if you put 1 kilogram, there is no response, but the scale, if you put 1 gram, the reaction will be strong. Let’s just say that the balance is highly sensitive for weighing. Typically, within the linear range of a pressure transmitter, the higher the sensitivity of the transmitter, the better. This is because only when the sensitivity is high, the value of the output signal corresponding to the change to be measured is relatively large, which is conducive to signal processing. However, 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 interference signal introduced from the outside world. Due to the material performance of the detection components and the performance of electronic components, as well as environmental factors and other factors, it is impossible for some instruments in practical applications to have linear sensitivity in the entire range, even if the same type of instrument, different models have different sensitivity. In the design and selection of the instrument can not blindly pursue the high sensitivity of the instrument, the high sensitivity of the instrument price, so we in the selection of the instrument to consider comprehensively, in order to meet the production requirements of the premise, consider the instrument with sufficient sensitivity.
