WirelessHART Solutions

WirelessHART solutions provide a flexible way to add measurement points where wiring is impractical, expensive, or constantly changing. Built around a wireless mesh concept, they integrate field values into monitoring systems using a gateway as the bridge between the wireless network and the host application. The approach supports both greenfield deployments and incremental upgrades of existing installations.

A key advantage is suitability for systems that expand regularly or include moving assets. WirelessHART can be applied in frequently modified installations (for example, well heads), as well as on rotating or moving machinery where cable routing is difficult. Because the network is self‑organizing, it requires minimal time to set up, integrate, and commission compared with running new cable infrastructure.

A typical WirelessHART system comprises a gateway connected to the monitoring system and up to 250 WirelessHART field devices. Adapter concepts allow WirelessHART communication to be added quickly to existing HART or 4–20 mA devices, bringing legacy measurement points into a wireless network without replacing the primary instrument. Devices transmit measured values at defined intervals to the gateway, which collects them and makes them available to a connected application; configuration can be performed using FieldCare device configuration software.

Benefits include rapid deployment, the ability to bridge obstacles and reach difficult‑to‑access points, and an economical path to expanding measurement coverage. The same characteristics make it suitable for temporary campaigns (e.g., diagnostics or optimization studies) and for permanent additions where the installation footprint must remain light. By upgrading legacy loops, WirelessHART can increase visibility without disrupting existing control strategies.

Typical applications include condition monitoring on rotating equipment, additional temperature/pressure points on remote piping, and supplemental measurements on mobile or modular skids. It is also used to extend instrumentation in brownfield areas where conduit capacity is limited, where hot work must be minimized, or where access constraints make traditional wiring projects slow and risky.
