Do you know what the test machine requires for sensor performance?

The test machine sensor is mainly used for testing. Its main test objects are metal and non-metal materials. A good quality tester sensor can help us test the stretching and bending of materials and so on. So, do you know what the test machine requires for sensor performance?

Accuracy is an important performance indicator of the test machine sensor, which is directly related to the accuracy of the test results. The higher the accuracy of the general test machine sensor, the more expensive it is. Therefore, the customer must select the test machine sensor according to the actual situation, the sensor accuracy meets the accuracy requirements of the measurement system.

The frequency characteristics of the test machine sensor directly determine the frequency range of the material being measured. It is necessary to adhere to the distortion within a permissible frequency range to meet the requirements. In fact, the response of the test machine sensor will have a certain delay, in short, the shorter the delay time, the better.

The linear range refers to the range in which the output is proportional to the input. In theory, the linear range of the tester sensor is relatively stable. The wider the linear range of the tester sensor, the larger the range and the accuracy of the measurement. However, it is impossible to guarantee the absolute linearity of any tester sensor. When the requested measurement accuracy is low, the tester sensor with less nonlinear error can be approximated as linear, which brings great measurement. Bento.

If a tester's sensor is still able to guarantee its constant performance after a period of use, its stability is good. In general, there are two main factors affecting the long-term stability of the test machine sensor: one is its own structure; the other is the working environment of the test machine sensor. Therefore, the test machine sensor should have strong environmental adaptability.

In the linear range of the tester's sensor, everyone wants the higher the flexibility of the tester's sensor. Since the higher the degree of flexibility, the value of the output signal corresponding to the measured change is larger, which is advantageous for signal processing.

The above is the test machine's performance requirements for the sensor, and we must also pay attention to the higher the flexibility of the test machine sensor, the greater the impact of external noise. Therefore, when selecting the tester sensor, it should ensure the compatibility between flexibility and the amount of external interference.
