Resistance based Temperature Sensor > 0-5v input

[Lyle_57IAL]

Hey Guys,

Currently looking at logging oil temperatures to my S300 0-5v inputs. Seems quite hard to find a actual 0-5v oil(fluid) temperature sensor - If anyone knows of one please let me know !

However I have herd that it is possible to convert a resistance based temperature sensor in conjunction with a extra resistor and some supplied voltage to convert the signal to a 0-5v value.

Does anyone have a bit more information or a wiring diagram on how this would be done? and if it would also be possible to add to a sensor that was being used by a aftermarket gauge already?

Cheers guys:)

It may be what your looking for.

This will be available for the S300 very shortly (I've added it in the last week).

The supported sensors are the Bosch 0280130026 (ECT) & 0280130039 (IAT) and the Delphi TS10075 (ECT) and Delphi 25036751 (IAT). All sensors are really common and cheap ($15-$20), and there are many sensors in each family with the same resistances. There are variants with straight threads + crush washers and also NPT sensors. You'll need a 1.5k 1% ohm pull resistor.

Details, including wiring, will be available when the software is released, which should be in the next week.

Yes I am chasing a sensor for oil temperature though. And would this just simply be using one of the six analogue inputs ?

[Hondata]

Use an ECT sensor for oil temperature. Do you mean one of the 8 analog inputs on the s300? (6?)

Very interested in this

[Lyle_57IAL]

Yes thats correct. Apologies one of the 8 analogue inputs. But could you post a wiring diagram on how to wire the resistance based fluid temperature sensor with the pull-up resistor etc

Hi Hondata

is a oem D16 ECT sensor scaled the same as the following. Would the ECT sensor or any of the below be suitable for oil temperature? If i used the OEM honda D16 ECT sensor what pull-up resistor would i need?

• Delphi 25036751 (air temperature)
• Delphi TS10075 (coolant temperature)
• Bosch 0280130039 (air temperature)
• Bosch 0280130026 (coolant temperature)

Thanks

I did not calibrate the D16 ECT.
Either the Delphi TS10075 or Bosch 0280130026 will work for oil temperature.

We are using a AEM Pull Up Temp sensor for oil temp has an almost linear output that can easily be corrected if using the 2 extra inputs on the ecu itself that can be calibrated with multiple point. The shortcoming is the slow response time.
