Omega thermocouple (4 conductors)

#1: Post by **akirapuff** » January 4th, 2020, 1:02 am

I just bought an omega thermocouple to run artisan ( this one: https://www.omega.com/en-us/sensors-and ... -1-8-U-6-B ) ( also, https://www.omega.com/en-us/wire-and-ca ... 4SSPC-RF-2) The thermocouple is connected through a 4 pin connector to that wire, which has 4 conductors coming out of it.

I am trying to connect it to phidget 1048. Did I buy the wrong thermocouple? I didn't know it comes with 4 wires...

It looks like that housing can be ordered with one or two thermocouples installed, so 4 wires. If you only have one thermocouple I would guess you'll only use one of the pairs of wires. I'd use an ohm meter to see which one's connected or if they are both connected, or just hook it up and see what it says.

Edit: Looks like you want to use the purple and red wires. But, I see this note when I delve further:

Designed to Be Used With All of Omega's M12 Enabled RTD and Thermistor Temperature Sensors

Which makes me wonder what device you've purchased.

On second thought, I might have been looking at the wrong M12 cables since I see that you aimed at an M12 thermocouple.

the wire colors are black, white, brown, light blue. any clue?

Here is my 1048. I have 3 K type thermocouples coming in. The 1048 can take 4 t/c's. Each thermcouple is comprised of 2 wires

If you have a volt meter with a thermocouple range or a really low DC voltage range I'd just try measuring all possible combinations, if not that try ohms as a thermocouple will likely measure close to a short. Once you figure out which wires are likely the thermocouple, hook them up to your board and see what happens when you warm up the sensor. You can't hurt anything by connecting them backwards. Weird that they don't seem to document the pin outs. Or just call them in the morning, they've always been real helpful when I've called.

And if you get lost enough, bring it over and I'll figure it out for you, I'm in Los Angeles too. PM if you want that.

According the datasheet for your thermocouple, that's the wrong cable...

I believe this is the one you need.

Thank you Jake! let me try that one.

No problem!
Let us know how it works out.
