WirelessHART technology from Pepperl+Fuchs offers the ideal solution for the described requirements and replaces the wired installation. Due to the short distances of up to 20 m between the individual field devices, signals can be transmitted easily to the process control system via a gateway.
For fast and easy retrofitting of existing field devices, the WirelessHART adapter from Pepperl+Fuchs is the perfect solution. It allows any conventional 4 mA … 20 mA or HART field device to be smoothly upgraded. The adapter reads the data from the field device via HART protocol or converts the 4 mA … 20 mA signal into a digital value and forwards this to the WirelessHART network. The connected field devices are powered by the adapter's battery.
If a new temperature measurement device is needed, users can deploy one single WirelessHART field device: the WirelessHART temperature converter. This field device is already equipped with a WirelessHART interface. As the battery voltage does not have to be converted, the WirelessHART temperature converter is more efficient than a combination of an adapter and a conventional field device. The WirelessHART temperature converters offer two connections for temperature sensors such as resistance thermometers and thermocouples.
