Certain parts of these interactive displays determine their durability.
The back shell of many HMIs is made from plastic. It makes the HMI lightweight and easy to mount in many places. Plastic protects the inside parts from dust and small debris. Though not as strong as metal, plastic holds up well in normal-use factories. It also resists rust, which can be an issue in humid areas. Plastic lasts long when cared for.
Many models have a glass front panel. This tempered glass provides a strong and clear surface for touch inputs. Tempered glass is much stronger than normal glass in stopping harmful rays, scratches, and impacts. It keeps its clarity over time and is easy to wipe down. The sleek surface improves the look of the screen too. Glass may also have anti-glare on it to help see it in bright light conditions.
Some large HMIs use aluminum frames for extra strength and light weight. The aluminum helps the HMI withstand bumps, drops, and other strong forces in tough work settings. Aluminum also resists rust better than steel does. This metal keeps the screen safe inside for many years.
These HMIs come with silicone seals that protect them inside. Silicone gaskets keep the areas between parts tight to stop dust, water, and other things from getting inside. This helps the HMI stay safe in harsh areas and improves how long it lasts. The silicone fits well and has no small spaces where debris can stack up. It is a vital part in sealing all the joints to keep the screen clear and working properly.
Many businesses use these HMIs to automate and control processes.
Users in factories rely on them to automate tasks and boost production. Their ability to control machines from one screen speeds up operations. Workers use the touch screens to adjust settings, check data, and spot problems. This instant access helps the factories run smoothly and increase their output.
Users manage lighting, heating, and cooling systems in big buildings with these screens. They adjust the different systems to keep people comfortable. The screens give managers an overview of all the building systems on one display. This simplification of management helps save energy and keep the place running efficiently.
These HMIs give users in plants control over their production processes. Users watch vital process data and make quick adjustments to keep things on track. The screens provide real-time feedback, allowing users to catch issues fast. This process monitoring helps maintain quality and limits production downtime.
Businesses in many sectors keep an eye on machines with these touch screens. They track machine performance and catch any issues early. Users can set up alerts to notify them of problems before they disrupt work. This constant monitoring helps reduce repairs needed and keeps machines running at their best.
Users manage inventory levels and track items in warehouses using these HMIs. They quickly update stock records with the touch of a screen. The screens give users a live look at stock levels and where things are located. This real-time data helps logistics teams avoid shortages or overstocking. It streamlines their inventory tasks and keeps operations moving smoothly.
Certain key factors affect the durability and quality of these interactive screens.
Their IP65 rating helps these models resist water and dust well. This rating lets them operate even in wet or dusty areas. The screens keep working smoothly, so users do not have to worry about bad weather ruining them. This rating also means less screen upkeep for users.
These HMIs work well across a wide range of temperatures. They keep doing their job no matter if it is hot or cold out. This range lets users use them in many different settings without fear of overheating or freezing. They take the heat and cold, so users know they will work in any weather. They keep going strong, making them dependable in various climates.
Their ability to absorb shocks lets them handle rough use in places like trucks or machines. They stay intact even when the screen experiences jolts or vibrations. This durability means users do not have to replace screens often from wear and tear. They suffer impacts without damage, so their performance level does not decrease over time. The screens perform reliably in tough conditions.
Their anti-scratch and glare coating keeps the screens clear and in good shape. Users can touch the screen without it scratching easy. The glare shield lets users see the screen well in bright light. This coating gives users an excellent view of the screen, allowing them to control tasks with accuracy. Even after years of use, the screen remains unharmed, and its quality stays as high as new.
These coatings also reduce the need for frequent maintenance or replacement.
When choosing these interactive displays, buyers consider these factors.
Buyers should pick a screen size that matches the tasks at hand. Large screens are good for managing complex jobs, while small ones work for simple tasks. The screen size also impacts how the touch screen fits in existing setups, so it is vital for buyers to measure available spaces first.
Buyers should ensure the model they choose communicates well with other devices. So, they should get one that supports common protocols like Modbus or PROFIBUS. This will make integrating the screen with other factory devices so much easier.
Buyers must consider the environment in which the HMI will operate. Screens for outdoor use should have good dust and water resistance. Users in extreme heat or cold will also need a model built to handle these conditions.
Buyers should check that the HMI software works well with the PLCs they already use. Compatibility will ensure setup goes smoothly without needing extra steps. They should also look for software that is user-friendly so workers can learn it fast and manage tasks with ease. More importantly, they should ensure the software supports easy visualization for important data displays.
Buyers should choose a touch technology that fits their needs. Resistive touchscreens are better for harsh environments, while capacitive screens have a more modern feel. They should decide whether they need multi-touch support. This factor allows more complex gestures that can enhance user interaction during critical tasks.
The model and make are the obvious factors that affect the price, along with the size of the screen. The materials and technologies used are important too. The touch sensitivity and screen resolution, as well as the environmental rating, also come into play.
Moreover, the number of units ordered directly impacts the cost. Buyers should remember that ordering more often brings a much better per-unit price. Lastly, whether the product has extra features such as alarms or charts and software compatibility can also affect the price.
Users can increase the life of their screens by regularly cleaning them. Users should make sure to clean them gently with the right materials. Moreover, using a screen protector can reduce scratches from constant touching or dirt.
Furthermore, regular maintenance of the internal parts helps users avoid swift breakdowns or problems. Users should take care to keep the screen in a moderate-temperature environment. Preventing it from overheating helps extend its lifetime as well.
Most PC touchscreen HMIs cannot support more than one user at a time. This fact is mainly because they have resistive touch screens. When multiple users try to interact with these screens at the same time, it often leads to incorrect inputs. This outcome annoys and frustrates the users as the screen mistakenly interprets the touches.
Moreover, even though some touch screen technologies have been created to support multi-touch, not all HMIs use these technologies. It means that most industrial HMIs use simpler touch technologies that cannot support simultaneous users. Therefore, the best way to guarantee effective interaction is to allow a single user to operate the panel at a time.
These HMIs have many useful features that make the maintenance job easier for users. For example, they can monitor their internal temperatures and send alerts if it seems like they are getting too warm. They also measure how much work the touch screens do, so users know when to give them a break.
Moreover, the touchscreen displays check themselves regularly for problems. They can send alerts if something inside seems to be breaking down. It is also common for the HMIs to have reminders for things like software updates. This feature ensures they always run the newest programs.
Almost all of them come with some kind of warranty or promise about their quality. The length and coverage of the warranty can depend on the brand, though. Some warranties cover everything, while others only protect against certain kinds of defects.
However, just because a warranty is shorter does not mean the product is lower quality. Even screens with short warranties often undergo testing to make sure they can stand up to tough jobs. So, users should look at both the warranty and how well the screen performs to judge its quality.
