As shown on the scheme to the right, the heater R
sensor R
essential to determine the correct values of the resistors R1,
R2, and R3. The bridge is in balance as soon as the desired
temperature difference between R
30K. At a changing flow the bridge voltage U_Bs needs to be
controlled in dependence of the bridge balance V1-V2. The
values for R1…R3 are depending on the temperature
difference
We will provide you with the values of R1…R3 , depending
on the application.
For calibration the R2 needs to be adjusted within a range of
The method of adjustment relies on the application.
