Abstract
A simple, rugged, reliable, low cost temperature display-cum-controlle r has been designed and constructed using standard integrated circuits and a 3 1/2 digit LED display. The controller, utilising semiconducto r controlled rectifiers as fast solid state on-off switches capable of maintaining the set temperature constant within the temperature range -200-degrees-C to +200-degrees-C with a resolution of +/-0.05-degrees -C. A thermocouple (specifically, a copper-constantan type) sensor has been used because of its fast response time and tolerance of high mag netic fields.
