Abstract

Manómetro para la medición de sobrepresiones, de vacío y de presiones diferenciales con una estructura (2a, 2b, 2c) de membrana, que subdivide herméticamente una cavidad definida en una carcasa (1) del aparato en al menos dos cámaras (3,4) y cuyo movimiento de desplazamiento generado en función de las presiones de las cámaras puede ser transmitido por medio de un elemento (17, 18, 40) de acoplamiento a un mecanismo (35) de relojería de un dispositivo de presentación analógico y con una disposición de resortes, que actúa sobre la estructura (2a, 2b, 2c) de membrana, por medio de la que se puede ajustar a priori el margen de medida del manómetro, al mismo tiempo, que la disposición de resortes comprende al menos un resorte (13) de medida, que puede ser llevado de forma centrada al apoyo en la estructura (2a, 2b, 2c) de membrana y al menos un resorte (8) auxiliar dispuesto en el otro lado de la estructura (2a, 2b, 2c) de membrana axialmente con relaciónal resorte (13) de medida y que fija la estructura (2a, 2b, 2c) de membrana entre sí y el resorte (13) de medida, caracterizado porque el resorte (8) auxiliar apoya en una sufridera (9) desplazable a lo largo de él, por medio de la que se puede ajustar la fuerza de pretensado del resorte (8) auxiliar aplicada a la estructura (2a, 2b, 2c) de membrana.
