16 mA = 100 % Measuring range
Error value: 3 mA (±3 μA)
Calculation of measurement value x in mm from analog current
Reference value SMR: Reference value MMR:
x [mm] = (I

- 4 mA)* - MR/2
MR [mm]
16 [mA]
Example: Measuring range = 10 mm, I
OUT
= 12 mA; Result: x = 5 mm respectively x = 0 mm
7.3 Digital Value Output
The digital measurement values are issued as unsigned digital values (raw values).
