Abstract
METODO PARA COMPENSAR LA TEMPERATURA DE UN INDICADOR DE POSICION. COMPRENDE: A) SUPERVISAR LA TEMPERATURA DEL ELEMENTO QUE SE DESPLAZA ENTRE UNAS PRIMERAS Y SEGUNDAS POSICIONES MEDIANTE UN INDICADOR DE POSICION QUE LLEVA UN SENSOR QUE EMITE UNA SEÑAL DE SALIDA DE REGISTRO DE ELEMENTO; B) GENERAR UNA REPRESENTACION ELECTRICA DE UNA CORRIENTE DE DESVIACION RESPECTO A UNA TEMPERATURA DE REFERENCIA REQUERIDA PARA EL COMPONENTE DE DESVIACION DE LA SEÑAL DE SALIDA DEL SENSOR A LA TEMPERATURA DEL ELEMENTO; C) PRODUCIR UNA REPRESENTACION ELECTRICA DE UN FACTOR DE CORRECCION DE VELOCIDAD RESPECTO A UNA TEMPERATURA DE REFERENCIA REQUERIDA PARA LA VELOCIDAD DE INCREMENTO DE LA SEÑAL DE SALIDA DEL SENSOR A LA TEMPERATURA DEL ELEMENTO; D) PRODUCIR UNA SEÑAL DE CORRESPONDENCIA DEL ELEMENTO; E) FORMAR UNA REPRESENTACION ELECTRICA DEL PRODUCTO DE LA SEÑAL DE SALIDA DEL SENSOR Y DEL FACTOR DE CORRECCION A LA TEMPERATURA DEL ELEMENTO; Y F) AÑADIR A LA FORMACION DE E) UNA CORRECCION DE DESVIACION DE TEMPERATURA PARA COMPENSAR LA SEÑAL DE SALIDA DEL SENSOR. SE UTILIZA EN REACTORES NUCLEARES.
