The unit has a microcontroller. It will measure temp for more than one area. I want to use one of the temp inputs to measure the voltage of a 24v DC battery backup system. I want 24.0 degrees on the unit to equal 24.0 volts in the backup system. Since the thermistor has a value of 37.8K at...

I have a unit that measures temp with a thermistor. I want to use it to measure voltage. I am trying to build a circuit to emulate a thermistor. Here are the parameters. 24v control = 37.8K. 1v control change = -1k so there is an inverse relation ship. Control voltage range = ideal is 6...
