Abstract

Mejoras en los circuitos termosensibles caracterizadas por un circuito termosensible que comprende un interruptor de umbral monoestable de cristal, unos medios con respuesta a la corriente y un generador de forma de onda periódicas de tensión cuya salida se conecta a través de dicho interruptor a dichos medios con respuesta a la corriente y en el cual la corriente que pasa a través del interruptor, como resultado de la aplicación dal mismo de dicha forma de onda periódica, es una serie de impulso, cada uno de los cuales tiene una anchura que corresponde a la temperatura de dicho interruptor , con lo que la corriente media que pasa por dichos medios con respuesta a la corriente corresponde a la temperatura de dicho interruptor.
