Looking for 5 People to Experiment with Thermocouple/RTD Connectors

rscasny
rscasny over 5 years ago

What's the best way to connect a Thermocouple or an RTD probe to a printed circuit board (PCB). I was asked that question during a call I had with a supplier who manufactures thermocouple and RTD probes, among other things.image

 

It's not a question I am asked frequently. Hmm, good question: soldering, connectors, terminal blocks, etc.

 

At then end of that informative call, they decided to give me some of their new surface mounted Thermocouple/RTD probe connectors to give out to some interested members to experiment with.

 

Who I am Looking for

Anyone can apply by offering a comment below and tell me something about what you had in mind. I think if you were working on a temperature control/monitoring system and were using and connecting thermocouples/RTDs you would be great for this little project. But anyone who has a mind to experiment with these connectors is invited to offer their idea. I will send you some of the connectors to you.

 

I will send you some of these connectors. I'd like you to examine them, experiment with these connectors, and then write a blog on element14.

    For thermocouples, crimps etc introduce errors. Quality matching thermcouple connectors are a must. We use a lot of Type T and with careful selection and connection get better than 0.2c accuracy 0-140…

    Sean, Thanks for the reminder. I had to check with our shipping department to verify that we got the connectors delivered to the office. We got them. So, I will we shipping them on Monday. It's my understanding…

    Just to make the terminology clearer (because a search for binding posts for thermocouples won't reveal much). Really it's just plugs and sockets. You've got sockets which happen to be surface-mount (the…

    I am designing a PCB with several sensor interfaces to mate with a MKR Zero.

    It will include 3 K type thermocouples with the smaller connectors that should fit these PCB connectors.

    I am planning to use 3 Maxim interface chipMaxim interface chips to get accurate temperature readings/.

    The system will have an LCD display so it can display sensor data.

    rscasny Where can I find a datasheet showing PCB footprints etc for these TC connectors? I don't see a part number above.

    Blogging about the project would have to wait until the PCBs show up.

    Here's the datasheet I was given by the supplier:

    If you need something more, tell me. I'll call the supplier and get it for you.

     

    Thanks.

    I still haven't received these connectors. The mail seems quite messed up as I have 2 other overdue shipments from Newark that haven't arrived either. I haven't even got tracking numbers yet. It isn't just Newark though - most outstanding orders from other suppliers are also experiencing delays, but some are trickling in.
