Thick film measuring circuit gives superior accuracy to a conventional wire wound resistance. Measuring circuit consists of thick film ceramic tile with palladium gold or silver conductor pattern printed with resistive ink.
Laser trimming of measuring circuit guided by computer aided design data further improves accuracy.
Wiper arm and resistor pattern interface by silver or gold contact of phosphor bronze arm.
Acetyl copolymer body moulding with snap fit component assembly.
