For a product to be placed in the right context, durability, and material characteristics are very important in the right working environment. HMIs of Siemens are manufactured with concern for quality and are based on applications requiring high demand.
Water and Dust Resistance
A lot of 𝑆𝑖𝑚𝑒𝑛𝑠 𝐻𝑀𝐼𝑆 are certified with high IP (Ingress Protection) degrees, meaning they are created water and dust resistant. Commonly, touch screens have IP65 or higher ratings, ensuring protection against water jets and dust entry. This makes them especially suitable for outdoors and factory settings available where they face temperature, humidity, or dust exposure extremes.
Impact-Resistant Surfaces
The durability of human machine interfaces really comes in handy where environment-related factors are highly risky and there is a possibility of falling, heavy equipment, or sudden shocks. The screens used in Siemens HMIs are fetes with impact-resistant materials such as acryl or hardened glass. These materials do not only improve the operational safety of the interface but also increase the lifespan of the equipment.
Chemical Resistance
Plants' chemical exposure, for instance, in pharmaceutical or manufacturing industries, is most common. Screens of Siemens's human machine interfaces are coated with materials resisting chemicals like acids, solvents, and other reactive agents. This feature ensures that the interfaces remain functional even after a long time of exposure to hazardous substances.
Robust Housing
Other than screens, 𝑆𝑖𝑚𝑒𝑛𝑠 𝐻𝑀𝐼𝑆 devices are packaged in sturdy housings made of machined aluminum or reinforced plastics. These materials come with a lower ratio of weight to strength and attach the devices to impacts, vibrations, and general wear and tear. Robust housings also ensure proper functioning under extreme temperatures.
Temperature and Environmental Resistance
Many operating conditions affect the day-to-day running of any production facility. Hence, Siemens HMIs are designed to withstand extreme and variable temperatures. They are fitted with powerful cooling systems that help prevent overheating in hot working conditions. Similarly, the materials used for housing are thermally stable so normal operability is ensured even in temperature extremes.
Siemens HMIs are offered premium commercial value since they are important for industries to improve operating efficiency, decrease downtime, and secure operational safety. Key process areas in which Siemens HMIs add value include the following:
