The selection of the right cable or line for transmitting signals on your own machine has essential influence on the device availability. Usually, when determining the instruments of machines and plants, a profound quantity of attention is given to choosing the right sensors.
For example, an individual determines which measuring principles are employed for level measurement, which power should be provided to the machine and which kind of signal transmission ought to be used. Usually, the cables shown in the wiring schemes as simple connection lines between sensor and SPS are problematic. This poses a fascinating paradox in the automation technology ? a sensor is tested for highest demands to assure it meets the requirements of the application, whereas a cable is only seen as a component which supposedly guarantees a reliable connection under all circumstances.
However, cables and connectors pose the most frequent sources of error. ไดอะแฟรม is often where unforeseen potential for increasing machine availability can be found. During my course of research I learned that in a high two-digit percentage of most cases, renowned cable manufacturers traced back sensor failure on machines to mechanical failure of the cable because of faulty installation, handling and especially because of the choice of an unsuited cable for the precise application. Principally, there is absolutely no patent fix for determining which cable and which plug connector is best suitable for the application.
For เกจวัดแรงดัน , flexibility demands for cables used in level probes for level measurement in deep wells aren?t high, whereas the demands on tensile strength together with high longitudinal and transverse water tightness are. In level probes, plug connectors are barely ever applied due to the insufficient permanent leak tightness. For machine tools which are create in factory buildings, the simplest cable materials with a straightforward M12 connector are employed. In this case, however, the use of the right cable that permanently withstands ambient conditions such as temperature fluctuations and that features resistance against oils and fats can significantly increase the option of your machine.
The application of cable assemblies with factory pre-assembled connectors also prevents failure risk through improper on-site assembly. Therefore it is a fallacy that cables are the same and that any given cable with the sufficient amount of wires would work for an application.
In another of my previous articles, I drew up a brief overview of probably the most relevant criteria for choosing cables and connectors. Invest some time in specifying a suitable cable for your application. Think about the demands your plug connection to sensors and PLC must meet. An individually matched wiring concept offers a measurable increase of the machine availability and higher safety during operation.
