A
C-shaped ceramic is wound with copper or chromium-alloy wire as a
resistance element. Except for the slide contact surface, the entire
component is coated with a high-temperature, non-flammable resin.
After cooling and drying, insulation is applied through a high-temperature
process. Then, a centered rotating adjuster component is installed,
which slides along the resistance element and varies the resistance
to the desired value. The scope of the application includes educational
modeling, load simulations, industrial machinery RPM adjustment, voltage
and current adjustment, instruments, and automated control installations.
