Abstract

Un transmisor (36) de variable de proceso para medir una presión de un fluido de proceso incluye un acoplamiento de proceso que tiene una primera lumbrera (90) configurada para acoplarse con una primera presión de proceso y una segunda lumbrera (90) configurada para acoplarse con una segunda presión de proceso. Un sensor (56) de presión diferencial se acopla con la primera y segunda lumbreras y proporciona una salida relacionada con una presión diferencial entre la primera presión y la segunda presión. El primer y segundo sensores (97, 98) de presión se acoplan con la primera y segunda lumbreras respectivas y proporcionan salidas relacionadas con la primera y segunda presiones. La circuitería (72) del transmisor se configura para proporcionar una salida del transmisor de acuerdo con la salida del sensor de presión diferencial y/o el primer y segundo sensores de presión.
