WirelessHART
Group Overview:
WirelessHART
Wireless communication based on HART
With the following three components you can establish a convenient wireless communication:
- WirelessHART Gateway
- WirelessHART Adapter
- WirelessHART Temperature Converter
The WirelessHART Gateway is the core element of a WirelessHART Network.
The Network Manager determines the best primary and alternative paths between the single wireless sensors. It also determines which sensor is allowed to send a message on a specific channel. Network wireless communication is organized and optimized to provide the best performance in terms of speed, throughput and energy consumption.
The gateway provides the connection to DCS or Asset management systems with an Ethernet and RS485 interface, which can transfer data via HART or Modbus protocol.
The integration in DCS or AMS are done via DTM or DD.
The WirelessHART Adapter can be connected directly to the cable gland entry at any conventional HART or 4..20mA field device. The WirelessHART Adapter is battery powered. It supplies power to itself and the connected field device and provides maximum independence. The adapter operates continuously to provide the router functionality within the network. The field device is only powered when needed. Depending on power consumption, voltage requirements, measurement times and intervals between measurements, battery life can last for years.
WirelessHART Temperature Converter
The WirelessHART Temperature Converter provides two connections for temperature sensors (RTDs and TCs) and transmits the values directly into the network. The temperature converter is battery powered and also serves as a permanent router. Through user configured time intervals, the temperature measurements are performed and sent via the internal antenna. Depending on measurement intervals, battery life can last for years.
