What are Explosion Proof and Intrinsically Safe Durable Tablets.As industries increasingly invest in intelligent automation, asset management, and analytics, there remains a significant opportunity to enhance the on-site worker experience through cutting-edge technology. One such advancement is the introduction of durable tablets in environments traditionally deemed too hazardous for electronics due to explosion risks, where outdated paper-and-pen processes still prevail.
In these environments, a single electrical spark from unprotected tablets can potentially ignite explosive atmospheres, leading to disastrous consequences. However, by leveraging the right tools and technologies, we can equip our workforce with the necessary safeguards to minimize the chances of such catastrophes. This often leads to the question: What is the difference between Explosion-Proof (Ex) and Intrinsically Safe (IS) equipment?
Explosion-proof durable tablets are designed to withstand and contain any internal explosions that may occur within their housing. This means that if an explosion occurs inside the tablet due to ignition of gases, vapors, fibers, or dust within its enclosure, the explosion-proof design will prevent the flames and sparks from escaping and igniting the surrounding atmosphere.
The construction of explosion-proof tablets typically involves heavy-duty materials like cast aluminum or stainless steel, which have sufficient bulk and strength to suppress internal explosions. Additionally, the design ensures that the surface temperatures of the tablets remain below the ignition point of the surrounding gases or vapors.
On the other hand, intrinsically safe durable tablets operate on a fundamentally different principle. They are designed to eliminate the possibility of ignition in the first place by restricting the amount of electrical and thermal energy that can be generated or transmitted by the device. This is achieved through intrinsic barriers that limit the flow of current and voltage within the circuitry of the tablets.
Certification bodies like ATEX, IECEx, and NEC assess and certify intrinsically safe equipment for use in hazardous areas. These tablets operate at lower energy levels than explosion-proof devices, preventing the generation of sparks capable of igniting explosive atmospheres.
It is important to note that explosion-proof and intrinsically safe equipment serve different purposes and are not interchangeable. Explosion-proof tablets are focused on containing explosions within their robust housings, while intrinsically safe designs eliminate the risk of ignition altogether.
Moreover, intrinsically safe tablets often offer cost advantages over explosion-proof devices in terms of installation, operation, weight, and user flexibility. They are typically lighter and easier to integrate into various work environments, providing a more ergonomic and user-friendly experience.
Ultimately, the choice between explosion-proof and intrinsically safe durable tablets depends on the specific requirements of the hazardous area and the nature of the work being performed. Consulting with hazardous area engineers is crucial to determining which type of equipment best suits your worksite and ensures the safety of your workforce.
