The choice of the proper cable or line for transmitting signals on your machine has essential influence on the device availability. Usually, when determining ไดอะแฟรม ซีล of machines and plants, a profound amount of attention is given to deciding on the best sensors.
For ไดอะแฟรม , the user determines which measuring principles are employed for level measurement, which power should be provided to the device and which kind 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 a fascinating paradox in the automation technology ? a sensor is tested for highest demands to make sure it meets certain requirements of the application, whereas a cable is merely seen as a component which supposedly guarantees a reliable connection under all circumstances.
However, cables and connectors pose one of the frequent resources of error. This is exactly where unforeseen prospect of increasing machine availability can be found. During my course 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 due to the selection of an unsuited cable for the specific application. Principally, there is no patent remedy for determining which cable and which plug connector is most beneficial suitable for your 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 and 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 setup in factory buildings, the simplest cable materials with a simple M12 connector are employed. In this instance, however, the use of a suitable cable that permanently withstands ambient conditions such as temperature fluctuations and that has resistance against oils and fats can significantly increase the option of your machine.
The usage of cable assemblies with factory pre-assembled connectors also prevents failure risk through improper on-site assembly. It is therefore a fallacy that all cables are the same and that any given cable with the sufficient amount of wires is suitable for an application.
In one of my previous articles, I drew up a brief overview of the most relevant criteria for choosing cables and connectors. Invest some time in specifying the right cable for the application. Take into account the demands your plug link with sensors and PLC must meet. An individually matched wiring concept offers a measurable increase of the device availability and higher safety during operation.
