The Simply Explained video, “No-hassle wireless – with WirelessHART” demonstrates how the efficiency of a flue gas denitrification unit can be increased while at the same time saving costs.

Smart WirelessHART interface module with power supply for field devices

The WirelessHART Adapter SWA70 is an interface module for the wireless transmission of 4 to 20 mA/HART signals from connected field devices to a WirelessHART Fieldgate. It is powered by either a battery pack or power supply units. The WirelessHART Adapter can be used in hazardous and non-hazardous area for applications.
