Ci\u00f2 consente la misurazione di oggetti in ambienti ostili o in luoghi difficili da raggiungere. Il cambiamento rilevato nella riflettivit\u00e0 dal nero al bianco genera una transizione alla sua uscita. Questo TTL\/CMOS segnale compatibile pu\u00f2 essere utilizzato da un analizzatore di spettro, computer o contatore elettronico per fornire informazioni relative alle vibrazioni, velocit\u00e0 angolare o lineare della macchina in prova. L&#8217;alta velocit\u00e0 dell&#8217;unit\u00e0, 40 KHz, insieme alla sua piccola dimensione dello spot pu\u00f2 fornire un alto misure di risoluzione irraggiungibili con le tradizionali lampade a incandescenza tachimetri di origine. Un display LCD a sei cifre indica la velocit\u00e0 di passaggio del bianco\/scuro aree dell&#8217;encoder e registra i risultati in unit\u00e0 di giri per minuto, (RPM), giri al secondo, (RPS) o impulsi al secondo (PPA). La lettura viene aggiornata due volte al secondo. L&#8217;utente pu\u00f2 inserire il numero di impulsi per giro dell&#8217;encoder da utilizzare nel successivo calcoli. Possono variare da 1 impulso per giro a 255 impulsi per giro.<\/p>\n\n\n\n<h6 class=\"wp-block-heading\" id=\"h-la-lunghezza-d-onda-del-laser-impiegata-dall-unit-di-650-nm-visibile-arancione-rossastro-l-uso-del-visibile-la-luce-aiuta-l-utente-a-indirizzare-il-sistema-ottico-sul-punto-di-misurazione-di-interesse-consente-inoltre-l-uso-di-uno-spot-di-piccole-dimensioni-in-modo-da-poter-utilizzare-encoder-ad-alta-risoluzione\">La lunghezza d&#8217;onda del laser impiegata dall&#8217;unit\u00e0 \u00e8 di 650 nm (visibile arancione rossastro). L&#8217;uso del visibile la luce aiuta l&#8217;utente a indirizzare il sistema ottico sul punto di misurazione di interesse. Consente inoltre l&#8217;uso di uno spot di piccole dimensioni in modo da poter utilizzare encoder ad alta risoluzione. <\/h6>\n\n\n\n<h6 class=\"wp-block-heading\">L&#8217;LT-880 utilizza quattro batterie AA Ni-Mh che alimentano l&#8217;unit\u00e0 fino a dieci ore di funzionamento continuo. Pu\u00f2 anche funzionare da un alimentatore\/caricatore a parete. Il caricabatterie ha una velocit\u00e0 di ricarica rapida che pu\u00f2 caricare le batterie a piena capacit\u00e0 in circa 2 ore. <\/h6>\n\n\n\n<h6 class=\"wp-block-heading\">La testina ottica \u00e8 dotata di un cavo in fibra duplex lungo cinque metri. Altre lunghezze di fibra possono essere fornito fino a diverse centinaia di metri di lunghezza. Sono disponibili anche attacchi ad angolo retto. <\/h6>\n\n\n\n<h6 class=\"wp-block-heading\">L&#8217;uso di encoder ottici riflettenti appositamente fabbricati non \u00e8 necessario. Gli encoder possono essere realizzati con qualsiasi programma CAD e una stampante laser su normale carta bianca per fotocopiatrici.<\/h6>\n\n\n\n<h3 class=\"wp-block-heading\"><a href=\"https:\/\/rertech.it\/en\/products\/testing-and-maintenance\/fiber-optic-networks\/contactless-laser-speedometer\/\">Tachimetro laser contactless \u2014 RERTECH<\/a><\/h3>","protected":false},"excerpt":{"rendered":"<p>The LT-880 laser tachometer is a portable, battery-powered device that detects the passage of reflective materials\/anti-reflective markings on rotating or linearly moving machinery to determine the target&#039;s rotational speed or linear velocity.
