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

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.

Measuring & Monitoring
Temperature Corrosion
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
Level Control
 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

8. 9
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
