Not sure if this is the place to ask bit here goes. I have a temperature sending unit that has a resistance of 177 ohms at 212°F. I have a gauge that is looking for 40 ohms at 212°F. Is there a way to,make the gauge read the sender?

 

Probably not.
Do you have a schematic for the gauge?
Do you want to read all temperatures or do you just want to know the 212F point?

I do not have a schematic for the gauge. I do have the resistance values for the sending unit across the operating range.
This is for engine coolant temp in a streetrod and normal operating temp is near 210 so that is most important temp. The gauge manufacturer grudgingly gave me the set point resistance at 212 but that was it.

 

Something to read
I thought I could find a 40 ohm sender but could not. You could put 4.4 of the 177 ohm senders in parallel. (lol)
