Do you know what requirements the testing machine has for sensor performance? The testing machine sensor is mainly used for testing, and its primary testing objects are metal and non-metal materials. A high-quality testing machine sensor can effectively help us test the tensile and bending properties of materials, among others. So, do you know what requirements the testing machine has for sensor performance? Accuracy is an important performance indicator for testing machine sensors, as it directly affects the precision of the test results. Generally, the higher the accuracy of the testing machine sensor, the more expensive it is. Therefore, customers should choose testing machine sensors based on actual conditions.

The testing machine sensor is mainly used for testing, and its main testing objects are metal and non-metal materials. A high-quality testing machine sensor can help us effectively test the tensile and bending properties of materials, etc. So, do you know what requirements the testing machine has for sensor performance?

Accuracy isTesting machineAn important performance indicator of the sensor, which directly relates to the accuracy of the test results. Generally, the higher the accuracy of the testing machine sensor, the more expensive it is. Therefore, customers should chooseTesting machinethe sensor based on actual conditions, ensuring that the sensor's accuracy meets the measurement system's accuracy requirements.

Testing machineThe frequency characteristics of the sensor directly determine the frequency range of the measured material. It must maintain distortion-free performance within an allowable frequency range to meet requirements. In practice, the response of testing machine sensors will have a certain delay; in general, the shorter the delay time, the better.

The linear range refers to the range where the output is proportional to the input. Theoretically speaking,Testing machinethe linear range of the sensor is relatively stable. The wider the linear range of the testing machine sensor, the larger its measurement range, and it can ensure measurement accuracy. However, noTesting machinesensor can guarantee absolute linearity. When the requested measurement accuracy is relatively low, testing machine sensors with small non-linear errors can be approximated as linear, which greatly facilitates measurement.

If a testing machine sensor can still guarantee its unchanged performance after being used for a period of time, then its stability is good. In general, the long-term stability of testing machine sensors is mainly affected by two factors: one is its own structure; the other is the working environment of the testing machine sensor. Therefore, testing machine sensors should have strong environmental adaptability.

Within the linear range of the testing machine sensor, everyone hopes that the flexibility of the testing machine sensor is as high as possible. Because the higher the flexibility, the larger the output signal value corresponding to the changes in the measured object, which is beneficial for signal processing.

 

The above isTesting machinethe requirements for sensor performance. At the same time, we must also pay attention to the fact that the higher the flexibility of the testing machine sensor, the greater the influence of external noise. Therefore, when choosingTesting machinethe sensor, one should ensure the compatibility between flexibility and resistance to external interference.
