2.7 Electrical data
Connect the sensor only to intrinsically-safe certified circuits. Observe the following maximum
values for the sensor when connecting:
•
U
i
= 30 V
•
I
i
= 120 mA
•
P
i
= 1.0 W
•
L
i
= 10 µH
•
C
i
= 5 nF
CAUTION!
Capacity and inductance of the connecting cable have to be considered.
INFORMATION!
For information about rated data and the HART interface consult the standard documentation.
The internal intrinsically safe electrode circuit is limited to the following maximum values:
•
U
o
= 7.8 V
•
I
o
= 15.5 mA
•
P
o
= 30.5 mW
The connections for the intrinsically safe 4...20 mA sensor circuit are galvanically isolated from
the electrode circuit (test voltage 500 V
eff
).
