Condition monitoring in control cabinets Automation specialist Lütze has intro duced a new solution for temperature monitoring and efficiency improvement in industrial production. Condition monitoring of control cabinet temper- ature offers operators of systems and production lines a way to monitor, optimise and increase operational efficiency. Aiming to centrally monitor com- binations of multiple control cabinets equipped with the AirStream wiring system, the solution enables thermal monitoring through a single AirTemp controller unit. This central control not only improves monitoring efficiency but also minimises installation and maintenance. A key element of the solution is its cloud based implementation, which enables external access for operators to plants in various production sites worldwide. Users can access relevant data at any time and from any location, and adjust operating parameters as needed. The user-friendly AirTemp Monitor dashboard

allows real-time viewing of control cabinet temperature data, ensuring quick response to potential issues. The intelligent alarm system sends immediate notifications in case of mal- functions or over-temperature, allowing operators to proactively address critical conditions and prevent downtime. The AirTemp condition monitoring solu tion also incorporates demand-driven cooling: active cooling solutions can be connected to the system to influence cycle performance, enabling energy savings and reducing CO 2 emissions. Friedrich Lütze GmbH www.luetze.com OM3 is for enhanced 50/125 micron glass capable of supporting 10 Gb Ethernet over distances up to 300m and with higher speeds at shorter distances. It is optimised with a laser light source (VCSEL), which makes it capable of supporting higher speeds. OM4 is for enhanced 50/125 micron glass cable capable of supporting 10 Gb Ethernet over distances up to 550m. OM3 and OM4 are used in parallel optic protocols, which typically use four fibres in each direction to achieve higher speed links. OM5 is also for 50/125 micron glass cable, and can transmit 40-100 Gb, but can send multiple signals on one fibre over four different wavelengths, which means it can consolidate fibre use over a distance of 150m. OS levels are ideal for long distances while delivering information successfully. OM levels can have issues such as interference and signal loss, but use less heat and are cheaper.

Specifying OS and OM fibre When determining fibre optic cables such as those from Proterial Cable America (PCA) for a project, labels including OS1, OS2, OM1, OM2, OM3, OM4 and OM5 will appear. These labels are fibre optic cable designations that originated in the international ISO/IEC 11801 standard.

The ISO/IEC 11801 standard refers to international requirements for design ing, installing and managing structured cabling systems in customer premises. OS levels refer to single-mode optical fibre cables, while OM levels apply to multi-mode optical fibre cables. OS1 is usually tight-buffered and commonly used indoors, while OS2 applies to higher-performing, low-water peak single-mode glass. OS2 is a loose tube design and can be used outdoors. OM1 indicates standard 62.5/125 micron multimode glass. OM2 is standard 50/125 micron glass. Both OM1 and OM2 use an LED for light transmission but OM2 can handle higher bandwidth. Both OM1 and OM2 are typically used to extend legacy private networks.
