Up for sale is a used HP A Power Sensor as can be seen in the pictures. This item is in working condition, however, it’s sold as-is, as described. Nothing. A remarkable HP product, the HPA sensor. It appeared on the market about , and still today, these devices are very much thought.

Maybe if the reference is blown, and you replace it by a resistor, you could still get some readings from the power meter, with very much offset baseline, and accuracy would be gone anyway, but may still be usable for some test purposes. This site 84811a Akismet to reduce spam.

Note the capacity values — measures: Will try to attach a SMD 8481q some conductive epoxy. E-solder or other type of silver conductive glue may work for some few years on such substrate and geometry.
I had experience that the gold on sapphire substrate was totally dissolved by normal Sn-Pb solder.

Still, there are many sensors around that are blown — why do so many people hhp them to 0. It appeared on the market aboutand still today, these devices are very much thought after.

Never tried to use indium on sapphire substrate only used if for contacting ceramics-supraconductors. I just purchased some pure indium and would begin experiment several days later. SimonsDialogs — A wild collection of random thoughts, observations and learnings. Silver paste solder is an option?
Good idea to bypass one of the thermocouples. Quite some detail about this sensor can be found in the HP Journal, edition pages 19ff.

Absolutely, conductive silver epoxy is also used by in industrial production, fo GHz purposes. There is says that the sensor can withstand mW power, and even 0. Could the epoxy still have good conductivity in the several GHz and microwave 8481aa
