The first gauge you mention rings a bell. They were used on Canadian Calcamatic kilns. They were towards the centre of the panel which means they must have been part of the combustion control. What for I can’t remember. All the burner control was by Honeywell and GE. Selsyn were part of GE.
The second “thing” I haven’t a clue. I’ve worked on plenty of drum controllers, they used to fascinate me. Both the primary crusher and the washing section used them for auto start up.
Some PLC’s now have drum function blocks. I used them for the electric furnace you’ve seen pictures of. It replaced those crappy cam timers you made.
There’s something niggling me about this controller, was it used for speed control?
I haven't a clue what they were for.
We made them for Ashmore Benson & Pease (part of the Davy Ashmore Group) and they were branded ABP.
I Imagined the dial indicators to be mounted in a large panel fixed to a wall in some sort of control room to tell an operator what was happening somewhere else.
We made chart recorders as as well - paper on a roll like bog roll passing from one roll to another while an inky pen traced a wiggly line on it.
I seem to remember seeing - and engraving - the words "STOCK LEVEL INDICATOR" on something.
A lot of the stuff was engraved in Spanish but I didn't have to have a knowledge of the language to be able to engrave it onto an instrument dial !!
Those "crappy cam timers" used Honeywell micro switches except for one batch when Burgess persuaded our boss to give theirs a try. Now THEY were crap and we ended-up replacing them FOC with Honeywell.
It was a clear case of buy cheap, buy twice!
