Bosch0280130026 Pull-up Resistor

Postby Insomnia- » Sun Nov 13, 2022 1:34 pm

Hey there,

just installed my RT Dash2 and connected the first Sensor.
Bosch 0280130026 for Water Temp. chosen the Bosch Equation in the RT V10 for the Channel and added an 1K Resistor to the wiring.
Now i get -14°C on the Dash at ~12°C positive in the Room that Sensor sits.

Can i now simply add Resistors till i get the right Temp at the moment? Will that work throughout Water getting warm and cold?

Cheers
ELias

Have you installed this sensor with a cable supplied by Race Technology or did you make your own cable?

Then something in your wiring is incorrect. You must follow the connections or a "2-wire" sensor described here:

I'll double check that later.
Also will measure the resistor.. maybe i simply bought shit.
Ill be back, with a picture of the wiring.

Well, what can i say...
The "1kOhm" Resistors i bought simply werent 1k...

I had some other resistors and wired them up to 950Ohms and the Temperature went up to 12°C.
So everything looks good to me now. Gonna order some proper Resistors tho

Thannk you very much
