Abstract

An intrinsically safe in-line adapter with an integrated capacitive barrier for connecting a wireless module to an antenna. The in-line adapter (eg, N-type to N-type) can be designed to include intrinsically safe circuitry and an integrated capacitive barrier. Intrinsically safe circuits also include multilayer PCBs and the PCBs may be encapsulated and sealed with mechanical metal housings. Intrinsically safe capacitive barriers can be integrated with coaxial connectors and fitted as part of a fire enclosure to meet explosion safety standards and intrinsically safe requirements. Mechanical metal housings can be isolated by casings (e.g. rubber) to meet isolation requirements. The wireless module can be directly connected to the antenna by using an in-line adapter, via a coaxial connector, and without any special cable assembly.

Description

technical field [0001] Embodiments relate generally to intrinsically safe circuits and devices. Embodiments also relate to wireless devices. Embodiments additionally relate to intrinsic safe in-line adapters with integrated capacitive barriers for connecting wireless modules to antennas. Background technique [0002] In industrial process control systems, wireless networks are widely deployed to support sensing and monitoring of industrial processes. Such a network permits monitoring of industrial processes with wireless sensors without incurring the costs normally associated with wired devices. However, such wireless sensors generally need to comply with intrinsic safety standards in order to be used in certain applications. For example, a wireless sensor may need to meet a "Zone 2" (eg, moderately hazardous) or "Zone 0" (eg, highly hazardous) level of certification. [0003] Wireless sensors typically include RF (radio frequency) or other wireless radio boards together...
