Select the appropriate sensor is essential for testing machines

The sensor is an important test machine component , metallic and non-metallic materials, its tensile, bending , compression and shear accurate test , test machine without the support of the sensor . Testing machine sensor principle and structure of the measurement results for the test machine will have a huge impact , it directly affects the testing machine effect. The testing machine in the actual process , it is impossible from the testing machine test sensors alone . Testing machines currently on the market a wide range of sensors between products varied widely. So, we chose to test the sensor when the machine needs to pay attention to what it ? It requires what performance ? The frequency characteristic of the sensor unit sensor directly determines the frequency characteristics of the material being measured frequency range. Must be in a range of frequencies insist on not allowing distortion to meet the requirements . In fact, the sensor response test machine will have some delay , short delay time as short as possible . Sensor accuracy problems . The sensor is a precision tester important performance indicator, which is directly related to the accuracy of test results . Typically, the higher the accuracy of the sensor testing machine its price is more expensive . Therefore, customers in the selection test machine when the sensor , should according to the actual situation , the sensor accuracy to meet the measurement accuracy of the system requests it. Stability of the sensor . If the sensor is in the use of a test machine for a period of time and still be able to guarantee the same performance , its stability is good . Overall, the impact of long-term stability testing machine sensors there are two main factors: First, the structure itself ; Second test machine sensors work environment. Therefore , the testing Coolant Temperature Sensor to have a strong environmental adaptability . The linear range of the sensor . Sensor flexibility. In the test machine within the linear range of the sensor , the sensor test machine we all want flexibility better. Because flexibility is higher, and the measurement output signal corresponding to the change value was greater , it is a good signal processing . Meanwhile, we have to pay attention , flexibility tester sensor higher by external noise is greater. Therefore, the choice test machine sensors , it shall ensure flexibility and the amount of resistance to outside interference compatibility. Linear range refers to the output proportional to the input range . Theoretically, the linear range of Shaft Position Sensor testing machine is relatively stable . Testing machine wider the range of linear sensors , the greater its range , and measurement accuracy can be guaranteed . But any test machine sensors are not guarantee its absolute linear, when the requested measurement accuracy is relatively low, can be smaller nonlinearity tester approximated as a linear sensor , which brings great to measure bento . After the above analysis , select Auto Temperature Sensor tester is essential, must be carefully selected reconnaissance before screening, this test machine to be able to achieve the purpose of testing .
