Summary
[edit]Description00133 Barometro aneroide registratore.jpg |
Italiano: Sensore costituito da una serie di otto scatole sovrappposte che rendono più sensibile lo strumento alla variazione della pressione atmosferica, rispetto ad un semplice barometro con una sola scatola aneroide (cioè senza liquido). La somma delle flessioni delle singole scatole viene trasmessa ad un indice per mezzo di un sistema di leve che ne amplifica ulteriormente gli effetti. Ogni scatola, da cui è stata estratta l'aria, è a pareti sottili e ondulate e si schiaccia più o meno a seconda della pressione atmosferica. L'estremità dell'indice porta un pennino carico d'inchiostro, che scrive su un foglio di carta quadrettata. Un meccanismo ad orologeria muove il cilindro su cui è avvolta la carta, formando un diagramma temporale dell'andamento della pressiome atmosferica. La durata della registarazione è di una settimana e corrisponde ad un giro completo del cilindro. Nell'inchiostro vi è una piccola parte di glicerina per rallentarne l'evaporazione. |
