Heating elements

Post by SteveM » Fri Jun 08, 2018 1:07 pm

Here are some of what appear to be ceramic heating elements with nichrome heating wires.

Each has two sections with two halves.

One set is 4" OD and 7" long (3-1/2" each section).

The other set is 3-1/4" OD and 8" long (it's wrapped and I can't tell if it's one or two sections). The paper wrapping this is stained with what looks like ink.

The larger one is marked
Model 50301
Type 83sp unit
300 watts 57.5 volts ea.

The wire is 0.036".

I don't know if the wattage is for the entire unit, one round section or each half-round section.

Maybe they can be used for a small heating furnace for heat treating / annealing.

How does $50 plus shipping sound?

Measure the resistance to determine the power.

They would be handy to built a HT furnace. Guessing that the info applys to each section, unless the wire is continues between each piece. So 2 sections in series would use 110V, all 4 would use 220V. I have a HT furnace wired series/parallel. Uses 110v
