Relation between input current and calculated concentration

Figure 52 shows the output value depending on the input current, the set low value and the set high value with an input range of 020 mA.

Figure 52 Output value with an input range of 020 mA

1

Output value (concentration) (x-axis)

5

0 mA

 

 

 

 

2

OV=f(IC)

6

Low value (LV)

 

 

 

 

3

Input current (IC) (y-axis)

7

High value (HV)

 

 

 

 

4

20 mA

 

 

 

 

 

 

The output value (OV) is a function of the input current (IC).

The output value is determined according to formula (3):

HV-LV

(3) OV = f(IC) = IC ----------------- + LV

20mA

where: OV=Output value IC=Input current LV=Low value HV=High value
