Temp sensor that can be directley conected to the logo! 8 using 12volts DC?

------------------------------------------------------------------------------------------
Split from PT100 question - connect it with logo 0ba7 12/24 dc direct .

mattman110

is there any temp sensor or probe that can be directley conected to the logo! 8 using 12volts DC ?

 I think easier to buy a 0-10V sensor, instead of converters, resistors, etc.

Example for fluid temp; http://www.syxthsense.com/sensors/teat-lu/fluid-temperature-transmitter,-0..10v/

You can also get them as roomtemp sensors as well; http://www.syxthsense.com/sensors/0-to-10v-active-temperature-sensors/

 Looking into this as well. Not electronics guru, but sure this might work

And far cheaper than 48 pounds. Correct me, if i`m wrong.

 It will work indeed.

But resistors have tempco drift, and you will need to use more then one. 250 and 500 ohms are not in the standard E24 series (+/- 5%). IIRC it jumps from 240 to 270. And 470 to 560 ohms.

If your voltage are ie. 12,7V instead of 12.0V, you will again need to compensate in your LOGO!. It won't correct for cable lenght either.

Remember with LOGO! you have ~72 Kohm input impedance in parallel with your resistors to.

It's all up to your needs, what kind of precision/drift you can live with.
