Textile Testing Instruments Purchase and Use Points You Must Remember

2022-06-04 19:58

Due to the wide variety of Textile Testing Instruments with different performance and prices, as well as many manufacturers, when purchasing instruments, you should not only be familiar with the professional knowledge of textile material properties and product uses, but also understand the performance and characteristics of the instruments produced by each manufacturer. In-depth analysis and comparison, select the appropriate Textile Testing Instruments, so that it can not only meet the actual needs of production and scientific research, but also seek truth from facts to prevent blind comparisons and cause unnecessary economic waste.

In order to ensure that the measurement results of Textile Testing Instruments are correct and consistent, so that the measurement value is stable within a certain tolerance range, when purchasing and using the instrument, it is necessary to pay full attention to its good measurement performance and carry out necessary measurement verification. E.g:

(1) An instrument often has several ranges for selection. Generally, the error at both ends of the indication range of the instrument is large. Therefore, according to the different test objects, a reasonable and moderate instrument range should be selected.

(2) The precision of the instrument (accuracy for short) is a comprehensive reflection of the random error and systematic error of the instrument. In order to obtain the correct measurement results at the same time, an instrument with an appropriate precision level must be selected.

(3) The reproducibility of the instrument indicates the consistency of the same measured physical quantity under different measurement conditions. The so-called inter-station error or "station difference" is one of the reproducibility indicators. Therefore, when selecting an instrument, it is required to have Good reproducibility is important.

The development of modern instruments mostly adopts a serialized and standardized building block structure. It decomposes the instrument into several components and units with independent functions. Users can choose different unit combinations according to actual needs and different test requirements. It is convenient and economical.

In Textile Testing Instruments, most of the test object is a signal that changes over time, that is, a dynamic signal. If the output signal of an instrument can firmly track a rapidly fluctuating input signal without distortion, the instrument has a good dynamic response. Instruments with poor dynamic response performance will inevitably produce measurement errors. The factors that determine its dynamic response lie mainly in the sensor part. Therefore, the selection of sensors with excellent performance should be one of the important conditions to ensure the detection quality of textile instruments.

The development trend of Textile Testing Instruments is to widely use microcomputers. Therefore, whether it is centralized or dedicated, it is necessary to design interfaces and compile application software according to the characteristics of various instruments. This requires technical staff to be familiar with the testing process of textile instruments. Technical characteristics, but also have professional knowledge of computer applications. It includes the detection mechanism of textile instruments and the characteristics of input and output signals; the performance and usage of main interface devices; the basic method of compiling computer application programs, etc.
