Signal
For cable lengths over 250 m, the DDG requires a
transducer (amplifier) for signal amplification and a
24 V power supply unit, which can be supplied as an
accessory (Fig. 6).
NOTICE
The sensor is designed as PELV (Protective Extra
Low Voltage), i.e. the (internal) supply meets the
requirements for safe supply isolation. The GND
is connected to the housing.
NOTICE
This sensor is
not
suitable for fluids containing
oil!
