Pepperl and Fuchs will unveil its first Wirelesshart-enabled products at the 2009 Hanover Fair from 20-24 April.

Introductions will include a robust Wirelesshart gateway designed for the demanding operating conditions typical of the process industry, a Wirelesshart adapter designed to add wireless functionality to practically any conventional field device, as well as a self-contained Wirelesshart temperature sensor.

‘The introduction of the wireless version of the Hart protocol has provided the process world with a vital standard to enable all wireless field devices to communicate in the same language.

‘With these products, Pepperl and Fuchs’ initial aim is to help provide additional monitoring functions in existing process plants that would be impossible without the use of wireless communications,’ said Robert Schosker, Pepperl and Fuchs product manager.

Generally speaking, Wirelesshart is an extension of the existing Hart communications protocol.

This means that the standard is based on a proven technology with an installed base of more than 20 million field devices worldwide.

Pepperl and Fuchs’ Wirelesshart gateway will comply with the special requirements for operation in the Ex zone, and offer an RS485 interface, as well as an Ethernet interface for digital Hart signals.

Configuration will be possible via DTM, DD or built-in web server connectivity.

Models for Profibus and Foundation Fieldbus will be available at a later date.

Its Wirelesshart adapter will be able to obtain real-time signals from a measuring device or sensor at adjustable time intervals, and transfer them to the control system via wireless communication.

The Wirelesshart temperature sensor can be positioned at any location in the plant, and transfer up to two temperature values to the process control system.

Typical applications for Wirelesshart are parameter setting of field devices, and monitoring of uncritical process values and environment data.

In this field, wireless communication is the enabling technology of a range of applications that include performance monitoring, environment management and effective asset management with preventive maintenance strategies.

Compared with traditional wire-based Hart communication, Wirelesshart allows the integration of fixed process instruments, mobile field devices, temporary installations and remote sections of a process plant into the same communications infrastructure.

A major advantage is that Wirelesshart communication does not require any costly cable installations, and it enables users to monitor specific process parameters at locations where it has previously been impossible to do so.
