What are the basic requirements for commonly used sensors?

No matter what kind of sensor, as the pioneer who directly faces the test object, it must be able to realize the basic requirements of information conversion quickly, accurately, reliably and economically.

The working range and range of the sensor needs to be large enough to meet the extreme requirements of the corresponding test, need to have a certain overload capacity; must have the sensitivity and accuracy to meet the requirements, require the signal output after conversion and the input signal to be measured to be determined Relations, and the ratio is greater. Sensors also need to have fast response capabilities, stable and reliable work capabilities, longer life and lower costs, while maintenance, calibration is convenient. Depending on the specific field application, there are sometimes strict requirements on the size and weight of the sensor, and it is hoped that the internal noise will be less susceptible to external interference. Finally, it is better that the sensor output signal adopts a common standard form to facilitate interfacing with an external system.

It can be seen that choosing a suitable sensor is not easy, and it needs to be comprehensively considered according to requirements.
