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 level of attention is given to deciding on the best sensors.
For example, an individual determines which measuring principles are used for level measurement, which power supply ought to be provided to the device and which type 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 make sure it meets certain requirements of the application, whereas a cable is only regarded as a component which supposedly guarantees a trusted connection under all circumstances.
However, cables and connectors pose just about the most frequent sources of error. This is often where unforeseen prospect of increasing machine availability are available. 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 due to 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 most beneficial suitable for your 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 and also 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 setup in factory buildings, the easiest cable materials with a straightforward M12 connector are used. In pressure gauge octa , however, the usage of a suitable 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 utilization of cable assemblies with factory pre-assembled connectors also prevents failure risk through improper on-site assembly. It is therefore a fallacy that cables will be 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 short overview of probably the most relevant criteria for choosing cables and connectors. Take your time in specifying a suitable cable for your application. Think about the demands your plug link with sensors and PLC must meet. An individually matched wiring concept offers a measurable increase of the machine availability and higher safety during operation.
