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 directed at deciding on the best sensors.
For example, the user determines which measuring principles are employed for level measurement, which power supply should be provided to the machine 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 assure it meets the requirements of the application form, whereas a cable is merely regarded as a component which supposedly guarantees a trusted connection under all circumstances.
However, pressure gauge and connectors pose the most frequent sources of error. This is often where unforeseen potential for 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 due to faulty installation, handling and especially due to the choice of an unsuited cable for the specific application. Principally, there is absolutely no patent remedy for determining which cable and which plug connector is best suitable for your application.
For instance, flexibility demands for cables used 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 setup in factory buildings, the simplest cable materials with a straightforward M12 connector are employed. In cases like this, however, the usage of the right cable that permanently withstands ambient conditions such as temperature fluctuations and that has resistance against oils and fats can significantly increase the availability of your machine.
Using cable assemblies with factory pre-assembled connectors also prevents failure risk through improper on-site assembly. It is therefore a fallacy that all cables will be 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 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 connection to sensors and PLC must meet. diaphragm seal matched wiring concept supplies a measurable increase of the device availability and higher safety during operation.
