Example Actual
The instrument has a nominal measuring range (1) from 0 to 4 bar and
the instrument has an output signal from 4 to 20 mA (3).
Target
The customer would like:
the "Customer measuring range" (2) from 1 to 2 bar (25% of nominal
measuring range (1)
should correspond to the output signal from 4 to 20 mA (100%).
The scaling is 1: 4 (25% to 100%).
Inversion of the
output
signal The instrument provides the option of inverting the output signal (3).
The output signal
- 0 to 20 mA becomes output signal 20 to 0 mA
- 4 to 20 mA becomes output signal 20 to 4 mA
- 0 to 10 V becomes output signal 10 to 0 V
