Maximise Tetra Packaging Using the S12 Projected Capacitive Touchscreen PC

Global food demand increases yearly due to the growing population. In fact, by the year 2020, there will be a 30% increase in the global demand for packaged milk products (Tetra Pak Dairy index). To address this need, many aspects of the tetra packaging process are automated.


The automated process is monitored by industrial-grade computing devices. These devices are connected to sensors which can accurately determine the quality each product.


In addition, these devices function optimally regardless of its operating times. This is because of its excellent build quality and rugged features, such as its IP69K rating and NEMA sealing. This prevents water and loses by-products from damaging the internal components.

Tetra Pack Packaging Processes and Projected Capacitive Touchscreen PCs

Today’s food industry upholds the highest standard of quality. Food processing businesses must observe the safety and quality of their products. Monitoring all the processes takes an incredible amount of effort and focus when done manually.


Thankfully, advanced computing technologies allow the automation and observation of many complex processes involved. Technologies using industrial computers can process, segregate and monitor thousands of products simultaneously.


For example, industrial PCs with a projected capacitive touchscreen can monitor the product lines in the tetra pack packaging plant. And, by using these devices, operators can ensure the product’s quality throughout the processes.


With a streamlined packaging process, these industrial computing devices can assess the quality of products quickly and detect issues if any come up. Learn more details on this blog on how these devices can optimise the plant production and quality assessment.

Making the First Capacitive Touchscreen Meet Waterproofing Needs

Since before the introduction of the first capacitive touchscreen, exposure to water and moisture has posed problems for most electronics. That is until manufacturers started coming up with efficient waterproofing methods. Moisture and water causes damage to electronics and make operation of such devices in wet environments that much harder.

International Waterproofing Standards

Still, it would be wrong for companies to simply brand their products as waterproof. This is why there are international standards set for waterproofing. According to the International Electrotechnical Commission (IEC), devices that can be classified as waterproof must meet high Ingress Protection (IP) ratings. The highest achievable is IP-67 and such devices can be immersed in water up to 1m as well as handle exposure to dust.

Water Rejection and Wet Finger Tracking

There are primarily two subset definitions of waterproofing: water rejection and wet finger tracking. Water rejection is defined as the capacitive touch screen’s ability to reject false touches from occurring when liquid makes contact with the screen. At the same time, the screen should recover once the liquid has been removed.

Wet finger tracking, on the hand, refers to the touch screen’s capacity to track the position of a user’s finger even with the presence of water. It is well known that water on the screen affects the accuracy of touch when the screen is wet, and true waterproof screens will always maintain accuracy. The ideal number for tracking requirement in the presence of water is generally 1-2 mm.

Explaining Water Physics

Capacitive touch screen technology works through conductive touch. Because water is also conductive, this will make it more difficult for operation. To remedy this, waterproof touch screens make use of “self-cap” physics that allows the screen sensors to apply excitation signals to accurately sense the amount of charge it takes for the receiver.

Factors That Can Influence the Performance of a Projected Capacitive Touchscreen

The accuracy of a touch screen device is crucial in different settings. A screen that does not read or respond to touch accurately can cause a variety of problems. For one, a device may register the wrong commands. Imagine a medical testing lab where the panel computer does not register accurately. Such a situation may lead to false tests; and consequently, incorrect diagnoses.

The same applies to operating machinery. Wrong commands can cause injuries or other damages. An inaccurate touchscreen monitor wastes a lot of time, which impacts productivity. Inaccuracy when operating a touchscreen display can lead to bad data and that has serious implications.

Hand Positioning and User Interface

The hand positioning is one of the factors that influence the performance of a touchscreen monitor. The centre of a screen is said to be the most accurate part. Moving fingers to the right or left side of a display may reduce its sensitivity. The user interface will also impact performance. Varying touch screen technologies require different stimuli to operate. For example, a projected capacitive touchscreen monitor only requires a simple touch and it registers a signal. A resistive touch screen, however, needs pressure on the display for the same results.

Haptic Systems

Some modern touchscreen monitors have haptic systems that influence performance. Integrating a haptic system in a touchscreen device allows the user to feel the vibrations of tactile input. Input has improved accuracy when a user can feel every single touch. The systems also make eye-hand coordination tasks easier.

Gloved or Bare Hands

Touchscreen devices can be used with bare or gloved hands, but it will depend on the technology. Resistive touch screens allow the use of gloved hand because they don’t interfere with the pressure. Gloved hands, however, interfere with input on a capacitive display because there is no electrical charge passing through the gloves;however,some types of gloves are designed to act as conductors, making them usable on a projected capacitive touchscreen.
