Asked by: Gene1957
This will come with P/N: 2258 and the only thing you would need to supply would be the wiring.

Q: Regarding the 2258 sensor. I get that this is a NTC thermistor. As temp rises the resistance falls. I measured the resitance at room temp and found it to be 2250 ohms. I see some thermistors advertised as 10k sensors. Is the 2258 a 2.25K sensor?

Asked by: BHOLL this will be able to let you know the specs for our sensors. The 2258 is a 1123-20 ohm range. 2250 does sounds about right for room temperature.

Why not have oil temp option, only water temp

Asked by: Matttheman411
Thank you for your question. Due to the unique font used on this series, it uses its own screen for the dial face. Creating a new screen is significantly more expensive than one might expect, due to tooling and production costs. Unfortunately, at this time we do not have an oil temp screen available for this series. You could use the water temp gauge for oil temp, it will just say Water temp on the dial face.

what is air core ? if its mechanical why doesn't it say that

Thank you for reaching out to us. The 1737 is considered a short sweep electric. Air-Core is the type of electronic meter movement that floats freely and is not controlled by a physical spring. The mechanical option in our Old Tyme Black series is model 1733 -
