Industrial tablet computers need to be designed with wide temperature and humidity

In some places where the environment is extremely harsh, the application of industrial technology needs to adapt to environmental changes, such as the arctic with very low temperature, alpine regions or underground mines, etc. To ensure the normal operation of industrial panels, we must use industrial panels with a wide temperature design. , So why use industrial-grade tablet computers in extreme temperatures? Let's first look at the impact of high temperature and low temperature on industrial tablet PCs:

Industrial tablet computers

Industrial tablet overheating:

1. The heat reduces the resistance of the component, which increases the current flowing through the sensitive part. This increased electrical load not only generates more heat, but also deteriorates components over time.

2. Heat can damage the battery and reduce battery efficiency, which is especially serious for tablets and other devices. 3. Heat will also affect the platters on the hard drive, which may cause data to be unusable or damaged. Extreme temperatures can even melt the solder, which may cause the motherboard components to truly fall off.

Industrial Tablet PC is too cold:

1. The cooling circuit will expand and deform under the sudden burst of heat and electricity when the power is turned on.

2. Parts made of liquid crystal (such as LCD) will freeze and break.

3. The low temperature causes the hard disk drive to use fluid dynamic bearings to spin the physical hard disk platters. If the fluid in the bearing becomes thicker, the disc rotation speed will slow down, and the industrial tablet computer will write and retrieve data at a very slow rate.

4. Low temperature will produce more condensation inside the industrial tablet. This water may subsequently cause short circuits and corrosion.

Therefore, dedicated rugged industrial-grade tablet PCs or fanless mini PCs can operate at high and low temperatures and are not susceptible to these threats.

Industrial-grade tablets are usually designed to be fanless, which means that the cooling system of the device does not require moving parts. Fans are relatively small and fragile, and fanless industrial panel computers do not rely on its fans, and are usually composed of highly durable military-grade components that can handle a wider temperature range. Moreover, because industrial PCs and rugged tablet computers use low-power components specifically designed to prevent overheating, they are unlikely to reach high temperatures in the first place.

The sealed enclosure and fanless design also prevent condensation, and military-grade components are unlikely to be deformed. Finally, because rugged industrial tablets are usually equipped with more easy-to-use SSD hard drives, they do not have hard disk platters or fluid bearings, so they will not have a harmful effect on data storage.
