The right cable increases your machine availability

The selection of the proper cable or line for transmitting signals on your machine has essential influence on the device availability. Usually, when determining the instruments of machines and plants, a profound amount of attention is given to deciding on the best sensors.
For เกจ์วัดแรงดันแก๊ส , an individual determines which measuring principles are employed for level measurement, which power supply should be provided to the machine and which type of signal transmission should be used. Usually, the cables shown in the wiring schemes as simple connection lines between sensor and SPS are problematic. This poses an interesting paradox in the automation technology ? a sensor is tested for highest demands to assure it meets certain requirements of the application form, whereas a cable is only regarded as a component which supposedly guarantees a trusted connection under all circumstances.
However, cables and connectors pose one of the most frequent resources of error. This is exactly where unforeseen potential for increasing machine availability are available. During my span of research I learned that in a higher two-digit percentage of all cases, renowned cable manufacturers traced back sensor failure on machines to mechanical failure of the cable due to faulty installation, handling and especially as a result of selection of an unsuited cable for the specific application. Principally, there is absolutely no patent remedy for determining which cable and which plug connector is most beneficial suitable for the application.
For instance, flexibility demands for cables found in level probes for level measurement in deep wells aren?t high, whereas the demands on tensile strength as well as high longitudinal and transverse water tightness are. In level probes, plug connectors are barely ever applied as a result of insufficient permanent leak tightness. For machine tools which are set up in factory buildings, the simplest cable materials with a straightforward M12 connector are used. In cases like this, however, the use of a suitable cable that permanently withstands ambient conditions such as temperature fluctuations and that features resistance against oils and fats can significantly raise the availability of your machine.
The application of cable assemblies with factory pre-assembled connectors also prevents failure risk through improper on-site assembly. It is therefore a fallacy that cables are the same and that any given cable with the sufficient amount of wires is suitable for an application.
In another of my previous articles, I drew up a short overview of the most relevant criteria for choosing cables and connectors. Take your time in specifying a suitable cable for the application. Think about the demands your plug connection to sensors and PLC must meet. An individually matched wiring concept supplies a measurable increase of the machine availability and higher safety during operation.
