When it comes to working in hazardous environments, safety is of utmost importance. One essential tool that has become increasingly popular in these settings is the explosion proof tablet, also known as an ex tablet. These devices are designed to withstand the rigors of explosive atmospheres, ensuring that workers can access critical information and communicate effectively without compromising safety. In this comprehensive guide, we will explore the five key features to look for when purchasing an explosion proof tablet.
Intrinsically Safe Design
The first and most crucial feature of an ex tablet is its intrinsically safe design. Intrinsic safety is a protection method that ensures the device does not generate sufficient energy to cause an explosion, even in the presence of flammable gases or dust. When shopping for an explosion proof tablet, look for certifications such as ATEX, IECEx, or UL, which indicate that the device has been rigorously tested and approved for use in hazardous areas.
Explosion Proof Enclosure
An integral part of an ex tablet’s intrinsically safe design is its explosion proof enclosure. This protective housing is constructed from durable, non-sparking materials, such as stainless steel or aluminum, and is designed to contain any internal explosions, preventing them from igniting the surrounding atmosphere. The enclosure should also be sealed to prevent the ingress of flammable gases or dust, further enhancing the device’s safety.
Intrinsically Safe Components
In addition to the explosion proof enclosure, an ex tablet must feature intrinsically safe components. This includes the battery, display, and any internal circuitry. These components are designed to operate at low voltages and currents, minimizing the risk of spark generation. When evaluating an explosion proof tablet, ensure that all components are certified as intrinsically safe and compatible with the device’s overall protection method.
Rugged Construction
Given the harsh environments in which ex tablets are used, rugged construction is essential. Look for devices that are built to withstand drops, shocks, vibrations, and extreme temperatures. The tablet should have a reinforced housing, preferably with rubberized corners and edges to absorb impacts. Additionally, the screen should be protected by a strong, scratch-resistant material, such as Gorilla Glass, to prevent damage from daily wear and tear.
IP and MIL-STD Ratings
When assessing the ruggedness of an explosion proof tablet, pay attention to its Ingress Protection (IP) and Military Standard (MIL-STD) ratings. The IP rating indicates the device’s resistance to dust and water, with higher numbers signifying better protection. For example, an IP68 rated tablet can withstand complete dust ingress and prolonged immersion in water. MIL-STD ratings, such as MIL-STD-810G, certify that the device has been tested against a range of environmental stressors, including temperature extremes, humidity, and vibration.
Rugged Connectors and Ports
An often-overlooked aspect of rugged construction is the durability of the tablet’s connectors and ports. These components are critical for charging, data transfer, and connecting peripherals, but they are also vulnerable to damage from dust, moisture, and physical stress. When choosing an ex tablet, look for devices with reinforced, sealed connectors and ports that can withstand the rigors of the work environment.
High-Performance Hardware
While safety and durability are paramount, an explosion proof tablet must also deliver high-performance hardware to support the demanding applications and workflows found in hazardous industries. Key hardware features to consider include:
Processor and RAM
A powerful processor and ample RAM are essential for running complex applications, such as real-time monitoring systems, 3D modeling software, and data analytics tools. Look for ex tablets with high-performance, multi-core processors and at least 8GB of RAM to ensure smooth, responsive operation.
Storage Capacity
Adequate storage capacity is crucial for storing large files, such as technical documents, manuals, and multimedia content. Opt for an explosion proof tablet with at least 128GB of internal storage, and consider models with expandable storage options, such as microSD card slots, for added flexibility.
Display Quality
A high-quality display is vital for viewing critical information, such as maps, schematics, and real-time data. Look for ex tablets with bright, high-resolution displays that offer good visibility in various lighting conditions. Consider factors such as screen size, pixel density, and color accuracy to ensure that the display meets your specific needs.
Battery Life
Long battery life is essential for maintaining productivity in the field, particularly in remote locations where access to power sources may be limited. When evaluating explosion proof tablets, look for devices with high-capacity batteries that can support a full shift of continuous use. Consider features such as fast charging and hot-swappable batteries, which can further extend the tablet’s operational time.
Connectivity Options
Seamless connectivity is crucial for enabling communication, data sharing, and remote access in hazardous environments. When selecting an ex tablet, consider the following connectivity options:
Wireless Connectivity
Wireless connectivity, such as Wi-Fi and Bluetooth, allows the tablet to connect to local networks and peripherals, enabling data transfer and communication with other devices. Ensure that the explosion proof tablet supports the latest wireless standards, such as Wi-Fi 6 and Bluetooth 5.0, for optimal performance and compatibility.
Cellular Connectivity
For applications that require remote access or communication beyond the local network, cellular connectivity is essential. Look for ex tablets that support 4G LTE or 5G networks, depending on the availability in your region. Consider factors such as carrier compatibility, global roaming support, and dual-SIM functionality to ensure that the tablet meets your specific connectivity needs.
Wired Connectivity
While wireless connectivity is convenient, wired options, such as Ethernet and USB ports, offer reliable, high-speed data transfer and compatibility with a wide range of peripherals. When choosing an explosion proof tablet, look for models with rugged, sealed ports that support the necessary wired connectivity options for your workflow.
Software and Security
The software and security features of an ex tablet are just as important as its hardware capabilities. Consider the following aspects when making your purchase decision:
Operating System
The operating system (OS) of an explosion proof tablet determines its compatibility with various applications, as well as its overall user experience. Popular options include Android and Windows, each with their own strengths and ecosystems. Consider factors such as application availability, user familiarity, and update support when selecting an OS for your ex tablet.
Security Features
Given the sensitive nature of the data handled in hazardous environments, robust security features are essential. Look for ex tablets that offer hardware-level encryption, secure boot, and biometric authentication options, such as fingerprint scanners or facial recognition. Additionally, consider the device’s compatibility with enterprise security solutions, such as mobile device management (MDM) platforms, to ensure that it can be integrated into your organization’s security framework.
Software Customization and Support
Many industries have specific software requirements that may necessitate customization or special support. When evaluating explosion proof tablets, consider the manufacturer’s ability to provide custom software solutions, such as pre-installed applications or bespoke user interfaces. Additionally, assess the level of software support offered, including the frequency of updates, bug fixes, and security patches, to ensure that the device remains secure and up-to-date throughout its lifecycle.
Conclusion
Choosing the right explosion proof tablet is a critical decision that can significantly impact the safety, efficiency, and productivity of your operations in hazardous environments. By prioritizing the five key features outlined in this guide – intrinsically safe design, rugged construction, high-performance hardware, connectivity options, and software and security – you can select an ex tablet that meets the unique needs of your industry and workforce.
Remember to thoroughly evaluate each aspect of the tablet, from its certifications and ratings to its hardware specifications and software capabilities.
