Abstract

Un transmisor de temperatura de proceso industrial (100) para medir una temperatura de un medio de proceso (102) incluye una unidad de detección de temperatura (104), un circuito de compensación (120) y un circuito de salida (126). La unidad de detección de temperatura incluye un sensor de temperatura de proceso (105A) que está separado del medio de proceso por una pared de aislamiento (108). La unidad de detección de temperatura (104) está configurada para producir una señal de temperatura (122) que es indicativa de la temperatura del medio de proceso (108) con base en una salida de señal de temperatura de proceso (106A) desde el sensor de temperatura de proceso (105A) durante una medición de temperatura. El circuito de compensación (120) está configurado para compensar la señal de temperatura (106A) durante un tiempo de respuesta de la medición de temperatura a un cambio en la temperatura del medio de proceso (102), y emitir una señal de temperatura compensada (122). El circuito de salida (126) está configurado para producir una salida de temperatura (128) como una función de la señal de temperatura compensada (122) correspondiente a la temperatura del medio de proceso (108).
