Phobya 71225 G1/4" Inline Temperature Sensor

Quadcells

Hello,
I picked one up to use as inline water temp sensor for the water cooling of a Chimera+.
All the data I have on it is that it is a 10k ohm sensor.
I tried this but the reading is 2000.C

M305 P106 X6 T10000 B4725 R4700 H0 L0 S"Water Temperature"

I measured the sensor with an ohm meter and it was about 15k at 14.3 degrees C.

What Duet are you using, what version of RRF?

Here is my complete heaters and thermistors code:

OK,
did some more testing and I found this this to work, but a little confused why it does:

M305 P106 X6 T10000 B4725 R4700 H0 L0 S"Coolent Temperature"

to this:

M305 P106 X4 T10000 B3950 R4700 H0 L0 S"Coolent Temperature"

and moved the temp sensor to P4 on the Duex5 board.

Did I have to move the temp sensor to P4 and change X6 to X4 because I used a virtual heater P106 and they go in order as the next available P channel ? just want to understand why it works the way it does.

No, it should have worked using X6 and sensor input E6_TEMP.

User error.
Not to make excuses, but my eye sight close up is not what it used to be. Thinking that E6 is Thermistor 6 , after looking at the board layout online I notice that E6 is Thermistor 7 not 6.
So now I have the coolant thermistor plugged into E(5) Thermistor(6) and my code is:
