Value = (reading-a)/(b-a)*(d-c)+c

a = lowest value of the configuration

b = highest value of the configuration

c = lowest value of the range

d = highest value of the range

Output Configurations

The sensors/controllers are supplied from the factory (unless otherwise ordered) with

0...10VDC linear outputs for Out(1) and Out(2) (see Table I). If other options are

needed for the application, the output jumpers have to be configured before the unit

is powered up. Each jumper selection is independent from the others, except for the

“Start point selection” jumper, which affects both Out(1) and Out(2) linear outputs.

Alternative measuring ranges of the outputs can be selected with the software UIP

(version 4.3 or later).
