I wired this up wrong and do not understand how to do it correctly. See the attached pic. blue is +24V, white is dc common, yellow is the wire I need 0 – 10 volt for my Galil analog pickup. the value of the resistors is 1K ohm, two parallel made it 500 ohm.

I am getting 1.77 volts at room temperature, the same in the –10 freezer. temp sensor.jpg

Dam-mm, so I bought a sensor without the sensor (probe). Somethings these really cheap made in China components are not worth much.

Thanks.

I bought this probe off ebay:

may still need to confirm wiring. all I see on the probe is three colors of connectors. do not know what goes where.
