WirelessHART Solutions

WirelessHART solutions enable measurement points to be integrated into monitoring systems without running new signal cabling. Using the WirelessHART standard, instruments form a self-organizing mesh network that transports process values reliably to a central gateway, where the data can be consumed by automation systems, asset management tools, or monitoring applications.

The main benefit is flexibility. WirelessHART is well suited to assets that expand over time (such as wellheads or modular skids), installations that are constantly being reconfigured, and equipment that moves or rotates. Because the network organizes and repairs itself, the effort to set up, integrate, and commission new points is reduced compared with hardwired retrofits, especially where conduit routing, cable trays, or hazardous-area work permits drive cost and schedule.

A WirelessHART system typically includes a gateway connected to the monitoring system and a network of wireless field devices; Endress+Hauser solutions also use adapters that allow WirelessHART communication to be added to existing 4–20 mA or HART instruments. Devices transmit measured values at configured intervals to the gateway, which collects and exposes the data through standard interfaces. Network configuration can be performed with device configuration software, and the wireless layer can coexist with established hardwired control.

Typical applications include adding measurements behind physical obstacles, on remote or difficult-to-access equipment, and on temporary or mobile installations where wiring would be uneconomical. Common use cases are corrosion monitoring, valve or filter condition tracking, supplemental temperature and pressure points during turnarounds, and performance monitoring on rotating machinery. WirelessHART is also used to “upgrade legacy technology” by layering digital communications and diagnostics onto installed analog assets.

Successful deployment depends on network planning: gateway placement, antenna considerations, expected update rates, and the availability of routing nodes to maintain robust paths. Security settings and key management must align with site policies, and integration should be designed so wireless data is clearly identified and validated in the receiving system. When used in hazardous areas, ensure device and adapter certifications match the area classification and that installation practices preserve those approvals.
