Estos dispositivos se diferencian de los volt\u00edmetros anal\u00f3gicos tradicionales por su capacidad de mostrar valores de voltaje en n\u00fameros discretos en lugar de mediante la deflexi\u00f3n de un puntero, lo que los hace preferibles por su precisi\u00f3n y facilidad de lectura.<\/p>\n<h2>Conversi\u00f3n Anal\u00f3gica a Digital en DVM<\/h2>\n<p>El dise\u00f1o de los DVM suele basarse en un tipo especial de convertidor anal\u00f3gico a digital denominado convertidor integrador. Este tipo de convertidor, en su implementaci\u00f3n m\u00e1s b\u00e1sica conocida como convertidor de doble pendiente, utiliza un integrador en el cual se aplica un voltaje desconocido durante un per\u00edodo fijo (periodo de subida). Luego, se aplica un voltaje de referencia de polaridad opuesta hasta que la salida del integrador regresa a cero (periodo de bajada). El voltaje de entrada se calcula en funci\u00f3n del voltaje de referencia, el tiempo constante de subida y el tiempo medido de bajada. La medici\u00f3n del tiempo de bajada suele realizarse en unidades del reloj del convertidor, permitiendo que tiempos de integraci\u00f3n m\u00e1s largos resulten en mayores resoluciones.<\/p>\n<h2>Otros Tipos de Volt\u00edmetros<\/h2>\n<p>Adem\u00e1s del DVM, existen varios otros tipos de volt\u00edmetros, como:<\/p>\n<ul>\n<li>Volt\u00edmetro de Bobina M\u00f3vil de Im\u00e1n Permanente (PMMCM)<\/li>\n<li>Volt\u00edmetro de Hierro M\u00f3vil<\/li>\n<li>Electrodinam\u00f3metro<\/li>\n<li>Volt\u00edmetro de Tipo Rectificador<\/li>\n<li>Volt\u00edmetro de Inducci\u00f3n<\/li>\n<li>Volt\u00edmetro Electroest\u00e1tico<\/li>\n<\/ul>\n<h2>Simbolog\u00eda del Volt\u00edmetro<\/h2>\n<p>En los diagramas de circuitos, un volt\u00edmetro se representa con la letra V dentro de un c\u00edrculo, acompa\u00f1ado de dos l\u00edneas que emergen y representan los dos puntos de medici\u00f3n.<\/p>\n<h2>La Analog\u00eda Hidr\u00e1ulica del Volt\u00edmetro<\/h2>\n<p>La analog\u00eda hidr\u00e1ulica, o analog\u00eda fluido-el\u00e9ctrica, es una herramienta did\u00e1ctica \u00fatil para entender c\u00f3mo funcionan los circuitos, especialmente para aquellos que tienen dificultades con los conceptos de electricidad. En esta analog\u00eda, los componentes electr\u00f3nicos se representan con equivalentes hidr\u00e1ulicos. La relaci\u00f3n entre el voltaje y la corriente, definida por la Ley de Ohm, es an\u00e1loga a la ecuaci\u00f3n de Hagen-Poiseuille. Ambas son modelos lineales que relacionan el flujo y el potencial en sus respectivos sistemas. En esta analog\u00eda, el voltaje es equiparable a la diferencia de presi\u00f3n que impulsa el agua a trav\u00e9s de una manguera, y se mide en voltios (V). Este modelo asume que el agua fluye horizontalmente, ignorando la fuerza de gravedad, de modo que el volt\u00edmetro es equivalente a un medidor de diferencia de presi\u00f3n.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.electricity-magnetism.org\/wp-content\/uploads\/2022\/07\/digital-voltmeter-DVM-description.png\" alt=\"Digital Voltmeter - DVM\" \/><\/p>\n<div style=\"text-align: center;
