微測力傳感器由一個(gè)或多個(gè)能在受力后產(chǎn)生形變的彈性體,和能感應(yīng)這個(gè)形變量的電阻應(yīng)變片組成的電橋電路(如惠斯登電橋),以及能把電阻應(yīng)變片固定粘貼在彈性體上并能傳導(dǎo)應(yīng)變量的粘合劑測力傳感器和保護(hù)電子電路的密封膠等三大部分組成測力傳感器。
微測力傳感器在受到外力作用后,粘貼在彈性體的應(yīng)變片隨之產(chǎn)生形變引起電阻變化,電阻變化使組成的惠斯登電橋失去平衡輸出一個(gè)與外力成線性正比變化的電量電信號。美國Transducer Techniques HSW系列小型測力傳感器應(yīng)用:微型測力傳感器適用于空間有限的測力,廣泛應(yīng)用于工業(yè),科研等領(lǐng)域。
The HSW Series is hermetically sealed for use in harsh industrial environments. All ranges are made from 17-4ph heat treated stainless steel and incorporate a stainless steel molded connector system designed to resist wash down and most chemicals. The mating connector, sold separately, is available in three different cable lengths.
As with our SW0 Series, the Transducer HSW Series offers high accuracy, low deflection, fast frequency response, and good output (millivolt) compliance between tension and compression.
HSW系列是一款高密封型、適用于嚴(yán)苛環(huán)境下的稱重傳感器。材質(zhì)為17-4PH熱處理不銹鋼,
注入不銹鋼塑模,可抵抗沖洗和大多數(shù)化學(xué)腐蝕。其母接口可單獨(dú)購買,并帶有三種不同長度的電纜線。
HSW-2K系列 拉壓兩用式稱重傳感器
與SW0系列相比,HSW系列的精度更高,偏移度更低,頻率響應(yīng)更快,輸出電壓為毫伏級。
