1 DMT transducer
2 Controller
3 Meter
4 Recorder
5 24 V DC (16...30 V DC/40 V DC) power supply unit
6 4-20 mA current loop
IMPORTANT
• The signal inputs of all devices in the current loop must be
electrically isolated from the current output.
• Take into account the sum of the ohmic resistances of all
devices in the current loop (excluding power supply).
The input voltage of the transducer must never drop below
16 V during operation.
The measured value will otherwise be wrong.
