1 Sensor
2 HART resistance 250 Ω (optional depending on processing)
3 Connection cable with 2 mm pins and terminals
4 Processing system/PLC/Voltage supply
5 Interface adapter, for example VEGACONNECT 4
Note:
With power supply units with integrated HART resistance (internal
resistance approx. 250 Ω), an additional external resistance is not
necessary. This applies, e.g. to the VEGA instruments VEGATRENN
149A, VEGAMET 381, VEGAMET 391. Common Ex separators are
also usually equipped with a sufficient current limitation resistance. In
