What is the sensitivity of a sensor?

.

Sensor sensitivity is defined as the ratio of output increment to input increment.

Sensor, is a detection device, can feel the measured information, and can feel the information, according to a certain law transformed into electrical signals or other required forms of information output, in order to meet the requirements of information transmission, processing, storage, display, recording and control.

In order to illustrate the performance of the sensor, characteristics and input-output relationship, a series of test indicators, the main ones are: static model, linearity, sensitivity, hysteresis, repeatability, resolution, long-term stability, temperature stability, interference resistance, threshold (dead zone), total accuracy, frequency response characteristics, step response characteristics. The last two are dynamic indicators, the rest are static indicators.

Sensitivity is an important indicator of sensor performance indicators, refers to the sensor output increment to input increment ratio.

In practical applications, sensitivity can express the degree of amplification of the input signal sensor. For example, under the premise of the same range of input signal changes, the larger the range of output signal changes, the higher the sensitivity of the sensor.
