Both the new Sitrans P280 transmitter for pressure measurement and the Sitrans TF280 transmitter for temperature feature a WirelessHart interface and a graphical display with backlight function. They are easy to operate via push buttons. An integrated battery supplies the transmitters with power for more than five years, with the exact number of remaining days being shown. All other Siemens process instruments without WirelessHart interfaces can be integrated into WirelessHart communication with the Sitrans AW200 adapter. The adapter has an integrated battery which can also power a connected process instrument. If an external power supply is used, up to four conventional process instruments can be connected to the WirelessHart adapter simultaneously.

The new IE/WSN-PA LINK gateway manages the WirelessHart network with all its nodes and establishes the connection to the Simatic-based automation and control systems via Industrial Ethernet. The gateway is easy to configure via the integrated Web interface. Transmitter and adapter are commissioned and serviced using the Simatic PDM (Process Device Manager) which provides a simple, graphical and interactive quick-setup. With the Sitrans MDS (Maintenance Diagnostic Station) software, diagnostics data can be displayed transparently in a maintenance station, for example the wireless process instrumens and the devices connected to the Sitrans AW200 adapter.

The new WirelessHart product family is the result of collaboration by Siemens with the HART Communication Foundation (HCF). WirelessHart standard developed by HCF with the participation of Siemens, is the first industrial standard for wireless communication at the field level for use in the process industry. As a HCF member, Siemens played an important role right from the start in defining WirelessHart, contributing its comprehensive know-how and wide-reaching experience in process automation and wireless communication.

The new WirelessHart components are an integral element of the entire Industrial Wireless Communication portfolio from Siemens, available for a wide variety of sectors and covering a diverse range of industrial requirements regarding bandwidths, power consumption, safety and security, availability, distances to be covered and speed.
