I am considering building a platinum resistance thermometer, the probes are very expensive though.
There are some very affordable ones but they come with short tails.
Any idea how to connect to these ?
Solder would melt at service temp.

What temperature range do you want to measure? A thermocouple may be an easier option.

I have another thread discussing the thermocouple.
Range is as high as I can get, it's to get more confidence in the thermocouple readings.

Perhaps you could connect the platinum wires using something like this http://uk.rs-online.com/web/p/temperature-sensor-accessories/4553918/.

I just found some cheaper solutions by searching for "ceramic terminal block" on eBay.

Remember the HP Test equipment that used the ceramic terminal blocks?... I still have an HP 5" 5 MHz scope with those things in it...

Thanks for the replies, I have now found a supplier, however the package is very small and will probably be beyond the resolution of my printer and soldering ability.
Can anyone suggest a solution?

I know that adapter boards are sometimes to be found to other footprints, however please do not suggest eBay unless it someone you have personally dealt with and are happy with.

Fwiw I had a board for an Amtel project last year which i suspect had been immersion tinned,it was totally unsolderable,probably  because it had been stored too long, it cost me dear in lost components.

Look at dipmicro.com, they have a bunch of SMD adapters. I have a little stockpile of different sizes waiting to go into some project.

RS? Radio Shack, or something else?

RS components, Used to be Radio Spares I think.
V expensive.

Equivalent to Radio Shack over here would be Maplins.

Actually, prices at RS Components are generally not that bad. SMD adapters are an exception, because the only ones that RS (and Farnell) stock are the ridiculously expensive Roth Electronik ones. I get my SMD adapters from SparkFun distributors, Futurelec etc.
