The choice of the right cable or line for transmitting signals on your machine has essential influence on the machine availability. Usually, when determining ไดอะแฟรม ซีล of machines and plants, a profound quantity of attention is directed at deciding on the best sensors.
For example, the user determines which measuring principles are employed for level measurement, which power supply ought to be provided to the device 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. pressure gauge octa poses an interesting paradox in the automation technology ? a sensor is tested for highest demands to assure it meets the requirements of the application form, whereas a cable is only seen as a component which supposedly guarantees a trusted connection under all circumstances.
However, cables and connectors pose probably the most frequent resources of error. This is exactly where unforeseen potential for increasing machine availability can be found. During my span of research I learned that in a higher two-digit percentage of most cases, renowned cable manufacturers traced back sensor failure on machines to mechanical failure of the cable due to faulty installation, handling and especially because of the choice of an unsuited cable for the precise application. Principally, there is no patent fix for determining which cable and which plug connector is best suitable for the application.
For example, flexibility demands for cables found in level probes for level measurement in deep wells aren?t high, whereas the demands on tensile strength along with high longitudinal and transverse water tightness are. In level probes, plug connectors are barely ever applied because of the lack of permanent leak tightness. For machine tools which are set up in factory buildings, the easiest cable materials with a simple M12 connector are employed. In this instance, however, the usage of the right cable that permanently withstands ambient conditions such as for example temperature fluctuations and that features resistance against oils and fats can significantly raise the availability of your machine.
The usage of cable assemblies with factory pre-assembled connectors also prevents failure risk through improper on-site assembly. Therefore it is a fallacy that all cables will be the same and that any given cable with the sufficient number of wires is suitable for an application.
In another 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 a suitable cable for your 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.
