Armature Temperature Measurement on DC motor

[Masbibe]

Hello guys,

Is anybody saw this kind of armature temperature measurement on DC motor (see attached photo).

We should upgrade drive for this motor with new one, and hopefully we should keep temperature measurement.

Anybody has idea what this resistance frequency converter is doing here ?

Good to know, Scotty!
There's sometimes a need for such a device. Can you remember who makes/sells it?

Ours were proprietary parts on a seam welder made by Solid State Equipment Corp. (SSEC). It was a temperamental machine at best, and most of the time it wasn't at its best. Probably late 1980's / early 1990's vintage. The photo below shows one of the welding electrodes and its slip ring housing above the blue keypad. This one looks like it has been run very hot so the liquid metal has probably failed (like ours did).

From a quick look on Google:

for new products.

Scotty - That looks like some snake oil to me.

Gunnar - All this electronics stuff is way above my pay grade.

Muthu - you should discuss that with your employer. It is only us self-employed that can accept such a situation...

Edison,

Could be! Maybe we were really handling mercury in 1996, even though we were told it was a safer replacement. The stuff we removed from the electrode was thick and lumpy, while the fresh material looked very like mercury.

I have no knowledge of Mercotac's products - that was from Google - so if it's snake oil then you have my apologies!
