Figure 51 shows the output current depending on the process value, the set low value
and the set high value with an output range of 4
–20 mA.
The output current is determined according to formula (2):
(2)
where:
OC=Output current
PV=Process value
LV=Low value
HV=High value
Figure 51 Output current with an output range of 4
–20mA
1 Output current (OC) (y-axis) 5 Low value (LV)
2 OC=f(PV) 6 0mA
3 Process value (PV) (x-axis) 7 4 mA
4 High value (HV) 8 20 mA
