The output value (OV) is a function of the input current (IC).
The output value is determined according to formula (3) :
where:
OV=Output value
IC=Input current
LV=Low value
HV=High value
Figure 54 shows the output value depending on the input current, the set low value and
the set high value with an input range of 4 – 20 mA.
Figure 53 Output value with an input range of 0 – 20 mA
1 Output value (concentration) (x-axis) 5 0 mA
2 OV=f(IC) 6 0 mA
3 Input current (IC) (y-axis) 7 0 mA
4 20 mA 8 0 mA
(3) OV = f(IC) = IC ×
HV – LV
