So what is WirelessHART?
WirelessHART: Is an open & interoperable standard Is based on the established HART protocol Uses known tools and procedures for configuration, maintenance, & diagnosis Requires minimal training Allows wireless access to existing field devices Can be used worldwide without any license
A Network that works
The WirelessHART network is a mesh network where each sensor acts as both a router and repeater. The range of the network doesnt depend on the location of the central gateway, allowing set up of large distributed network structures.

Intelligent Network Structure
If there is an interrupted communication path, the system automatically re-routes the signal in order to maintain uninterrupted communication.

The WirelessHART gateway is the core element of a wireless mesh network. It serves as the interface between the mesh network and the plants process control or asset management.
The WirelessHART adapter can be connected directly to the interface of any field device. This can be a conventional 420 mA or an intelligent HART device.
The WirelessHART Temperature converter offers two terminals to connect RTD or TC temperature sensors. It is designed to transfer measurements directly to the network.
Product Applications
Tank Farms Oil Refineries Rotational Equipment Mobile Equipment Ad hoc Monitoring Pipelines
Measuring & Monitoring
Temperature Corrosion Level Control
A simple WirelessHART temperature sensor can be used to detect & diagnose problem situations long before they result in failures & influence plant availability.
Ideal Applications or Locations Motors Pumps & cooling devices Resources that need monitors
WirelessHART monitoring instruments can be placed at important measurement points along pipelines in places that previously couldnt be reached.
Ideal Applications or Locations Long pipelines located in remote locations Plants with moving vehicles & changes in location
WirelessHART makes it easier & more cost effective to monitor the levels in process & storage tanks by eliminating the need to manually take & record the measurements.
Ideal Applications or Locations Storage vessels Process tanks
Lets Recap
We have learned that the benefits of WirelessHART are: WirelessHART networks are flexible, intelligent solutions for the requirements of the process industry WirelessHART components eliminate wiring & integrate conventional field devices into wireless structures Measuring & monitoring have never been more flexible or efficient, especially in remote locations WirelessHART technology is here to stay, and those who adapt early will reap the benefits
