What Is a Tube Marker?
A tube marker is used to print symbols on cables in specific construction projects. They are not often used in general construction sites but are used when connecting cables to terminal blocks of control panels for sequence control and the like. If the cables are not marked, it is necessary to trace each cable to its destination, which is a major hassle. In addition, when tags are attached to each cable as in the past, there are problems such as deterioration of the tags and tags sticking to small areas.
Uses of Tube Markers
As mentioned above, tube markers are used for printing symbols on cables. The use of tube markers allows more space for wiring, and the finished product is thought to look better visually. This will make periodic maintenance and inspection easier, improve the visibility of complex terminal blocks, and increase the efficiency of checking work. Although tube markers are becoming more common, with higher performance and lower cost, they are nonetheless still expensive and there are few specialists in the use of tube markers.
Principle of Tube Markers
Tube markers can be broadly classified into two types: those with limited printing functions and those with multiple functions. The limited-function type has the sole function of printing on the marker tube and is usually manually operated. On the other hand, multi-functional models are equipped with high-speed printing functions as well as other functions deemed necessary to improve work efficiency based on on-site surveys and research. For example, the built-in tube warmer prevents hardening of the tube by warming it during marking work at low temperatures in the winter, so that beautiful printing can be maintained. The system also uses a USB memory device as an external storage medium, making it easy to import data. The machine is also capable of setting up to 15 different sequential numbering options per document, including increasing, decreasing, and even alphabetical digit sequential numbering. Many are equipped with a large backlit display, making them easier to read. Most products are designed to operate under environmental conditions ranging from a minimum temperature of 5°C to 15°C (roughly 41°F to 59°F) and a maximum temperature of 35°C (95°F).
