Abstract (en)
[origin: GB2322273A] The resistive track of a thick film heater comprises at least two distinct sections connected by a bridge 11 of lower resistance material eg silver to avoid overheating at sharp bends. The width of the tracks 7a-7f may vary so as to maintain a constant temperature profile. The arrangement may define areas of differing heat levels as shown in fig 5 and the track conductivity may be varied by over/under printing with low resistance material 8. Low resistance bridges may be used to link tracks broken around obstructions such as connecting boss 13. Various terminal locations are disclosed.
