Feel somewhat disappointed today because I couldn't get a good soldered joint on my strain gages. I have a soldering iron for printed circuit boards and even careful handling the material that houses the gage it turned brittle while soldering and broke severing the gage. But I'm not giving up just yet. Ordered more gages with wire already attached to strain gage. Then will added the connectors along with some shrink tubing for insulation. This challenge is not over yet, chuckle.

That should work! I suppose you have looked at the low temperature alloy solders like the computer companies use. I read that some have a melting point less than 200C.

I'm using a soldering iron and small diameter soldering wire for printed circuit boards to attempt to attach the connector. The housing for the gage doesn't even like a small amount of heat applied to it. Whatever connection I can achieve doesn't need to be overly robust as gage and wire will be secured to the barrel by recommended epoxy. I'm itching to do some detailed PT testing with the 50 this year. For now I would be happy just to get operational and calibration done. It will eventually happen. Ed |
