小型、新型汽車、自動化和醫(yī)療應用的力傳感器解決方案

　　推還是拉？可能的話，如果是動作，而場是電子學，則需要一個力傳感器。簡單地說，力傳感器是將機械力輸入轉(zhuǎn)換成電輸出信號的傳感器。壓電式力傳感器用于諸如沖擊、高速壓縮、振蕩和張力等測量。

　　施加在傳感元件上的力影響材料的原子結構，導致電荷和輸出信號的分離。力傳感器用于各種汽車應用，如剎車、氣囊、速度控制、懸架和變速器。他們有廣泛的醫(yī)療、游戲、工業(yè)和航空航天用途。

　　有許多類型的傳感器測量力，傳感器內(nèi)的傳感器檢測事件的力量分為三大類：

　　應變計荷重傳感器

　　壓電晶體

　　通過壓力的測量

　　應變式稱重傳感器是最常用的力傳感器。應變計響應于所處的應變，而元件的形狀和彈性則構成施加力產(chǎn)生的應變的大小。應變計包括電阻應變片、箔應變計、薄膜應變計、半導體應變計和金屬絲應變計。應變計是用來測量靜力的。

　　Piezoelectric crystal force transducers are used with a charge amplifier to integrate the electric charges formed on a crystal surface to a given and measurable signal proportional to the force applied. These sensors are unique in that they are active sensors that do not require a power supply， and signals are easily generated without causing geometric changes to the force measurement route. They have a high-frequency response capability that makes them suitable for dynamic measurement， but because of leakage of charge from the charge amplifier， also called drift， they cannot perform static measurements accurately. They have small dimensions and can operate well within a wide temperature range， and are typically used to measure oscillation， impact， and high-speed tension and compression.
