Frequency response characteristics
The frequency response characteristics of the sensor determine the range of frequencies being measured and must remain undistorted within the permissible frequency range. In fact, the response of the sensor always has a certain delay, and it is desirable that the delay time is as short as possible.
The higher the frequency response of the sensor, the wider the range of measurable signal frequencies.
In dynamic measurement, the response characteristics should be based on the characteristics of the signal (steady state, transient, random, etc.) to avoid excessive errors.
Precision
Accuracy is an important performance indicator of the sensor, which is an important part of the measurement accuracy of the entire measurement system. The higher the accuracy of the sensor, the more expensive it is. Therefore, the accuracy of the sensor can be as long as it meets the accuracy requirements of the entire measurement system. This makes it possible to select a cheaper and simpler sensor Atlas air compressor accessory among the many sensors that meet the same measurement purpose.
If the purpose of the measurement is qualitative analysis, the sensor with high repeatability can be selected. It is not suitable to use absolute precision. If it is for quantitative analysis, accurate measurement must be obtained, and the sensor with the accuracy level can be selected.
For some special applications, if you can't choose the right sensor, you need to design and manufacture the sensor yourself. The performance of the home-made sensor should meet the requirements for use.
