Rated 5 out of 5 by from It works! Needed to replace my old sensor. Swapped it out and it works like it is suppose too. Its a pretty straight forward deal. Not much else to say. Highly recommended.

QUESTIONS:

I have a TPI Tech water temperature gauge that is reading too high. From what I have found the resistance should be 240-33. Do you make a sensor that would work with this gauge? Thank you!

Asked by: Falconman
We do not make a 240-33 ohm water temp sender.

Can you tell me ohms for this sensor at ambient temperature?  I’m trouble shooting since I have no readings. Let me know if I also need to check resistance at warm temperatures, too. Thx

Asked by: Srbob
Here is the link to the operational specs starting at 100 degrees. https://www.autometer.com/sensor_specs We don't have an ambient temp spec, but I'd expect 1300-1700 ohms. The most common issue with no reading on the gauge is because of a poor/insufficient ground for the sender. The threads of the sender must ground when installed. Excessive thread sealant, etc, can prevent that ground.

What are the dimensions of the temp sensor? My main concern is how far does it stick down past the mounting adapter. I am using the 16x1.5 male to 1/8 NPTF adapter.

Asked by: DogsLife
If you’re using our 2268 16MM adapter, our 2258 is fully compatible, but does not actually protrude out of the adapter. We’ve done extensive testing and this has no bearing on the accuracy of the reading.

Hi, any idea what the OHM reading is on your 2258 and 2259 senders please. Want to check I have the correct one

Asked by: Leprod
Hello Leprod, thank you for contacting us.The 2258 and 2259 resistance is the same and can be found here: https://www.autometer.com/sensor_specs. We have also identified these with a -27 (2258) and -28 (2259) etched into the sender as a means to differentiate from the senders we used up until the mid 90’s.

I have Phantom water temp gauge. Is this correct for sending unit.

Asked by: Old timer
Thank you for contacting us. This sender would be for the Short Sweep electric temperature gauge, like model 5737 or 5837. If you have a full sweep electric, like the 5754, that would require the 2252 sender.

Hello, please verify that the 2258 sender is the correct one for the Z Series 2639 Oil temp gauge. Will the 2259 sender work also? Is there any difference between the two except for the length? Thank you, Stan.

Asked by: SBBZ
Thank you for your question. The correct sender for 2639 is 2258. The only difference is 2258 has a longer probe.
