How to choose an Industrial PC - other considerations

Buying a new industrial computer can be a challenging task. It involves a great deal of analysis and can be challenging even for professionals. To make this process easier for you, specialists at STX Technology have covered 9 topics including Performance, Application, Operating System, Environment, Space, Mounting, Power, Connectivity and Accessories. In this article, we will discuss other considerations such as SSD size, IP rating compliance, the difference between types of enclosure finishes and types of touch screens.

What is the best SSD size for an industrial computer?

Selecting the most suitable size SSD (Solid-State Drive) for an industrial PC is very important to ensure that an adequate quantity of storage space is selected for your operational needs. Industrial computers don’t necessarily store much information on them, so a smaller size SSD may be sufficient. If your operational needs include running special applications or if you need to store a large quantity of files, then you would select a larger size SSD such as a 250GB or 512GB SSD.

The choice of an SSD over the more traditional HDD is often preferred in industrial environments due to the SSD’s lack of moving parts, offering more stable operation in applications where vibration may be a problem. In addition to this, Solid-State Drives produce less noise and are usually more energy-efficient. Computers with SSDs are often used in sterile and hazardous environments.

What is an IP rating and why you need to know?

An IP (ingress protection) rating is a standard that measures levels of sealing effectiveness for electrical enclosures against factors such as water, dust and moisture. When selecting an industrial computer, the relevant specifications will usually list the level of IP rating for that particular device. Purchasing a computer compliant with an IP rating ensures reliable operation in demanding conditions where humidity, dust, air-borne particles and water or moisture are a factor. The range of IP ratings extends from IP65 through to IP69K which offers the maximum level of protection. The first digit relates to physical intrusion of solid objects and things such as dust and air-borne particles. Number 1 offers no protection through to number 6 which indicates total protection against dust ingress. The second number refers to the moisture level protection or ingress of liquids. Once again, number 1 offers no protection through to number 8 which protects against long periods of immersion in water. Additionally, 9K will protect against close-range high pressure and high temperature spray downs. Check out our article about IP rating for more information.

What material are industrial computer enclosures usually manufactured in?

There are several different enclosure materials available for industrial computers, however two of the most common materials are stainless steel or aluminium. Stainless steel (304) is often a preferred option due to its toughness and its resistance to corrosion, harsh cleaning procedures and at times, rough handling by users. Marine grade (316) stainless is used when a higher level of protection is required to withstand salt, corrosive chemicals or industrial solvents. There is a selection of finishes available for stainless steel enclosures including brushed, highly polished, flat finish, anodised or powder coated. An aluminium enclosure offers a high level of protection and lower weight at the same time. Units built in aluminium can be manufactured in a brushed finish or in a range of colours to suit the project.

Projective Capacitive or Resistive Touch Screen?

All-in-one computers for industrial applications often have a touch screen as a standard option. This provides a quick and convenient option for data input, enabling easy and fast completion of tasks. It also removes the need for an IP rated external keyboard and mouse where space may be an issue. All industrial PCs and monitors manufactured by STX Technology have touch screens either with Projective Capacitive Touch (PCAP or PT) or Resistive Touch (RT).

Resistive touch screens are a tough and reliable mechanical touch system. Often preferred in an industrial environment, they offer the ability to operate the touch screen whilst wearing gloves or using a stylus. In certain applications damage can be caused by users operating the touch screens using sharp implements such as knives or metal probes. To help alleviate this problem, STX Technology offers the application of a tough sacrificial membrane to provide extra protection to the touch screen.

Projective Capacitive touch screens offer a strong touch system constructed of thick, industrial strength glass. PCAP screens are highly resistant to damage from accidental impact and from sharp objects such as knives and other implements. It is also possible to use a stylus to operate the PCAP screen.

As mentioned previously, selecting the right industrial computer can be a challenging process. There are many details to be considered before making a decision.
