富成國(guó)際

奧地利MESSTECHNIK-SCHALLER接近開關(guān)、SCHALLER傳感器、SCHALLER安全開關(guān)、SCHALLER電子開關(guān)。SCHALLER接近開關(guān)、SCHALLER傳感器是由奧地利梅斯-斯樂MESSTECHNIK SCHALLER公司生產(chǎn)的。 SCHALLER電感式接近開關(guān)屬于一種有開關(guān)量輸出的位置傳感器，它由LC高頻振蕩器和放大處理電路組成，利用金屬物體在接近這個(gè)能產(chǎn)生電磁場(chǎng)的振蕩感應(yīng)頭時(shí)，使物體內(nèi)部產(chǎn)生渦流。這個(gè)渦流反作用于接近開關(guān)，使SCHALLER接近開關(guān)振蕩能力衰減，內(nèi)部電路的參數(shù)發(fā)生變化，由此識(shí)別出有無金屬物體接近，進(jìn)而控制開關(guān)的通或斷。這種接近開關(guān)所能檢測(cè)的物體必須是金屬物體。SCHALLER電容式接近開關(guān)亦屬于一種具有開關(guān)量輸出的位置傳感器，它的測(cè)量頭通常是構(gòu)成電容器的一個(gè)極板，而另一個(gè)極板是物體的本身，當(dāng)物體移向接近開關(guān)時(shí)，物體和SCHALLER接近開關(guān)的介電常數(shù)發(fā)生變化，使得和測(cè)量頭相連的電路狀態(tài)也隨之發(fā)生變化，由此便可控制開關(guān)的接通和關(guān)斷。這種接近開關(guān)的檢測(cè)物體，并不限于金屬導(dǎo)體，也可以是絕緣的液體或粉狀物體,在檢測(cè)較低介電常數(shù)ε的物體時(shí)，可以順時(shí)針調(diào)節(jié)多圈電位器（位于開關(guān)后部）來增加感應(yīng)靈敏度，一般調(diào)節(jié)電位器使電容式的接近開關(guān)在0.7-0.8Sn的位置動(dòng)作。接近開關(guān)：CND32PDS……， Messtechnik Schaller GmbH Measurement devices for humidity and material moisture - dampness - water content FS_3 Biomass: Thanks to the development of FS_3 Biomass it is possible to measure the moisture content of wood chips, barks, wooden pellets, wood shavings and sawdust with one instrument by very simple handling. For data acquisition and analysis for billing we developed the software FS_3 View. RLF-TS: Discontinued Product! Support will be continued!
