It is well-known that important process and diagnosis information is often stranded in the instrument: inaccessible, unused and ultimately, worthless. This data can now be unlocked by using Endress+Hauser’s WirelessHART solutions, allowing users to make a quantum leap in plant availability and transparency.
The use of WirelessHART communication in process plants allow the user to benefit from its advantages without any loss of integrity:
* Monitoring of important but previously inaccessible measuring points.
* Asset management solutions.
* Inventory control in remote locations without an electrical infrastructure.
Endress+Hauser’s wireless portfolio comprises:
* WirelessHART Adapter.
* WirelessHART Fieldgate DTMs and DDs for system integration.
* Project management and engineering services to deploy WirelessHART projects.
The battery-powered WirelessHART Adapter can be added to any HART or 4-20 mA device, where necessary also providing the power. The adapter allows information from remote, difficult-to-access and mobile measuring points to be accessed centrally. This retrofit solution is particularly cost-effective.
The WirelessHART Fieldgate collects the data and integrates it into existing plant architectures through Modbus/OPC via Ethernet and RS485. The network is self-organising and self-healing, i.e. it detects broken data paths and finds alternatives routes.
