Abstract

TERMOMETRO ELECTRONICO. COMPRENDE DOS OSCILADORES DE CONSTRUCCION SIMILAR, ESTANDO UNO DE ELLOS (2) CONECTADO A UN ELEMENTO RESISTIVO (1) QUE ES PUESTO EN CONTACTO CON LA ZONA CUYA TEMPERATURA TX SE DESEA MEDIR, MIENTRAS QUE EL OTRO OSCILADOR (3) PROPORCIONA UNA FRECUENCIA FR DE REFERENCIA. ESTANDO AMBOS OSCILADORES A LA MISMA TEMPERATURA, CUANDO SE PRODUCE UN CAMBIO EN LA TEMPERATURA TX A MEDIR, VARIA LA FRECUENCIA FX DEL OSCILADOR CORRESPONDIENTE, REFLEJANDOSE ESTE CAMBIO EN UN CONJUNTO DE CIRCUITOS DIGITALES (4) MEDIANTE LA COMPARACION DE AMBAS FRECUENCIAS FX Y FR, LO QUE DETERMINA EL NUEVO VALOR DE LA TEMPERATURA TX.
