WirelessHART is an open standard for wireless communication that allows existing field devices to be accessed wirelessly. It uses a mesh network where each sensor acts as a router and repeater to extend the range of the network without depending on the location of the central gateway. If a communication path is interrupted, the system automatically re-routes signals to maintain uninterrupted communication. WirelessHART components eliminate the need for wiring and make measuring and monitoring more flexible, especially in remote locations.

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.

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.

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.
