1. A First Look at
WirelessHART
An e-book by Pepperl+Fuchs

2. So what is 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 2

3. 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 doesn’t depend on the location of the central gateway, allowing set up of large distributed network structures.

4. 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 plant’s process control or asset management.
The WirelessHART adapter can be connected directly to the interface of any field device. This can be a conventional 4…20 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. 5

7. 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
WirelessHART monitoring instruments can be placed at important measurement points along pipelines in places that previously couldn’t be reached.
Ideal Applications or Locations
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
Motors
Pumps & cooling devices
Resources that need monitors
Long pipelines located in remote locations
Plants with moving vehicles & changes in location
Storage vessels
Process tanks 6

8. Let’s 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
