Signal conditioning part 2 - Simple adjustment of 4-20mA HART sensors

Ralf Holl and Juan Garcia demonstrate simple operation and adjustment of 4-20mA Hart instruments when connected via Vegatrenn isolating transformers. These isolating transformers provide the sensor power supply and can be used as Ex isolators in hazardous areas. The Vegatrenn units also provide local display and diagnostics options, including Hart test jacks.
