Split-type instrument development prospects can be expected

Split-type instruments, as the name implies, separate the functions of each part of the instrument, each part is responsible for some functions, and finally, as a whole, the final result is displayed. There is no special requirement for on-site installation conditions. Why is the integrated instrument replaced?

One-piece instrument has weak adaptability to the site. The integrated instrument itself has all the functions of measurement, display, etc. The contact with the outside world must be the power measurement signal transmitted through the cable, but for the transmission line directly in contact with it, the integrated instrument It is completely impossible to control, any interference in the transmission process will directly affect the final measurement results. The split type instrument can separate the function of each part, this only needs to control the precision of the front end sensor to be able to control the precision of the whole test system, relatively the influence of the integrated instrument, outside world is relatively small.

Integrated instrument is difficult to control the precision of the system. The integrated instrument can do its own precision through technical updating, but the improvement can only be the accuracy of the instrument itself, but the user is ultimately concerned with the accuracy of the final measurement of the system. For the overall traceability of the system, integrated instrument manufacturers will not guarantee or guarantee. However, for split-type instruments, the overall traceability must be used. Split-type instrument manufacturers must ensure and also have the obligation to ensure the measurement accuracy of the entire system, because the front-end measurement, transmission line, or display instrument is provided by the manufacturer.

Integral instruments do not guarantee sufficient electrical safety because the direct contact with the all-in-one instrument is a cable for power signal transmission, so the integrated instrument and the sensor for front-end measurement are not completely electrically isolated. If the wiring is incorrect or there is a line abnormality, Theoretically, the high voltage and high current on the main circuit can be transmitted to the integrated instrument through the use of cables, directly damaging the instrument or even affecting personal safety. Therefore, there are too many uncertainties in one-piece instruments. Once a measurement problem occurs, this risk will be borne by the user.

Split-type instruments can be flexibly installed and used in the industrial field. There is no requirement for the on-site measurement environment, and the manufacturer of the split-type instrument is responsible for the measurement requirements of the overall system. For the user, there is no need to take any measurement risks. As long as measurement problems occur, it can be requested by a split instrument manufacturer.

With the advancement of industrialization, the advantage of split-type instruments will be greater and greater, and it will gradually replace the integrated ones in the industrial field and maximize the maximum functions of the measuring instruments.
