resistance Replicate thermistor behavior for second sensor


Posted on Feb 6, 2014

An R/C electric motor that has a 10K thermistor sensor built into it, which is connected to a speed control that has basic thermal protection. I would like to build a secondary sensor board that displays the temperature on a segment display, but I still want to pass it through to the speed control so that it still has thermal prot

ection. The issue I`m having is that the thermistor is only connected to ground on one end, no other reference potential, so I plan to read it with a voltage divider. This means I can`t just pass the end of the thermistor back through to the speed control, which may have its own voltage divider. Is there a way I can replicate the resistance of the thermistor to two different read circuits expecting a variable resistance
