Intrinsically Safe Wireless Access to Smart Field Devices

ATEXSierra delivers a certified, field-ready mobile HART communication solution that enables engineers to safely configure, diagnose, and validate HART-enabled field instruments directly inside Zone 1 hazardous environments. Using an intrinsically safe Bluetooth and USB interface paired with a Windows Zone 1 certified Aegex 100M tablet, this platform extends DCS and asset intelligence from the control room into the process area—while maintaining full compliance with international hazardous-area and regulatory standards.

System Architecture

The mobile HART solution integrates three certified layers into a unified operational system:

Field Layer
HART-enabled transmitters, positioners, and smart instruments installed in Zone 1 hazardous areas.

Communication Layer
ATEX-certified HART interface providing Bluetooth and Bluetooth Low Energy (BLE) connectivity for hazardous locations and USB connectivity for safe area operation.

Application Layer
Windows Zone 1 certified Aegex 100M tablet running advanced HART configuration and diagnostic software for real-time field access.
