Good day, 

I am trying to use a Wheatstone bridge to condition a thermistor. The arrangement i have is shown in below.

I need the following specifications.


10V output max from the bridge at maximum temperature (50 degrees celcius)
0V output max from the bridge at minimum temperature (0 degrees celcius)


I have determined the resistance of the thermistor at the minimum and maximum temperature to be as follows


At max temperature R = 174
At min temperature R = 1.1K


I know that for the wheatstone bridge to be balanced i need the following for my arrangement

R1/R3 = R2/Rt

So i have set R3 = 1.1K and Chose R1=R2=1500k (arbitrary value)

With this i do get 0V output at 0 degrees.

My problem is now, how do i ensure that the output voltage i get is 10V at 50 degree celcius, as i currently get 8.7V output with the source voltage set to 24V.

Any help would be appreciated, Thanks.


Question: Which color scheme to choose for applications that require long work hours?
Answer: I've always felt that for long copy, reversed text is really difficult to read but for long hours it's a godsend. Consider how most programmers look at their environment. There is a good reason for this:



The JetBrains Darcula theme has been exceedingly popular as it is both high contrast and desaturated. You can offer a similar option in midnight blues that is equally pleasing on the eyes. Note that we throw out the top and bottom 20% of the brightness scale as well.

Would I read a novel like this? Probably not. This style of interface is great for digesting blocks of information for hours on end. It's awful for paragraphs.
