available in two standard case
sizes and element types.
No end caps are used for the steel
element, terminations are welded
directly on to the steel slug. For the
Ceramic elements, tinned copper
wire leads are welded onto end
caps.
This manufacturing process allows
for very low resistance values to be
achieved.
The slugs are then finished by
applying three coats of light brown
epoxy resin.
