The following graphs show how the measuring range of each transducer version depends on the external reference

voltage value V

REF:

Upper limit: I

P = -40 x VREF + 185

REF = 2.5 .. 4 V)

Upper limit: I

P = -80 x VREF + 370

REF = 2.75 .. 4 V)

Upper limit: I

P = 85

REF = 0 .. 2.5 V)

Upper limit: I

P = 150

REF = 0 .. 2.75 V)

Lower limit: I

P = -40 x VREF + 15

REF = 0 .. 2.5 V)

Lower limit: I

P = -80 x VREF + 30

REF = 0 .. 2.25 V)

Lower limit: I

P = -85

P = -150

REF = 2.25 .. 4V)

Example with V

REF = 1.65 V:

Example with V

REF = 0 V:
