供應(yīng)德國FESTO傳感器,費斯托壓力傳感器

實際應(yīng)用 
                                力學傳感器的種類繁多,如電阻應(yīng)變片壓力傳感器、半導體應(yīng)變片壓力傳感器、壓阻式壓力傳感器、電感式壓力傳感器、電容式壓力傳感器、諧振式壓力傳感器及電容式加速度傳感器等。但應(yīng)用的是壓阻式壓力傳感器,它具有極低的價格和較高的精度以及較好的線性特性。下面我們主要介紹這類傳感器。[1]
                                  在了解壓阻式力傳感器時,我們首先認識一下電阻應(yīng)變片這種元件。電阻應(yīng)變片是一種將被測件上的應(yīng)變變化轉(zhuǎn)換成為一種電信號的敏感器件。它是壓阻式應(yīng)變傳感器的主要組成部分之一。電阻應(yīng)變片應(yīng)用zui多的是金屬電阻應(yīng)變片和半導體應(yīng)變片兩種。金屬電阻應(yīng)變片又有絲狀應(yīng)變片和金屬箔狀應(yīng)變片兩種。通常是將應(yīng)變片通過特殊的粘和劑緊密的粘合在產(chǎn)生力學應(yīng)變基體上,當基體受力發(fā)生應(yīng)力變化時,電阻應(yīng)變片也一起產(chǎn)生形變,使應(yīng)變片的阻值發(fā)生改變,從而使加在電阻上的電壓發(fā)生變化。這種應(yīng)變片在受力時產(chǎn)生的阻值變化通常較小,一般這種應(yīng)變片都組成應(yīng)變電橋,并通過后續(xù)的儀表放大器進行放大,再傳輸給處理電路(通常是A/D
                                轉(zhuǎn)換和CPU )顯示或執(zhí)行機構(gòu)。
                                  醫(yī)學常用的壓力參數(shù)有:血壓、顱內(nèi)壓、眼內(nèi)壓、腸內(nèi)壓、肺泡壓等,其中zui常規(guī)的測量內(nèi)容是血壓(Blood
                                Pressure
                                ,BP)。醫(yī)學上測量的血壓有動脈壓、靜脈壓和心內(nèi)壓(包括心室壓、心房壓)等,每種壓力信號又包括:收縮壓、舒張壓、平均壓。

                                  血管內(nèi)的血液在血管壁單位面積上垂直作用的力,稱為血壓。當人的心臟收縮時,動脈內(nèi)的壓力zui高,此時內(nèi)壁的壓力稱為收縮壓,亦稱高壓;心室舒張時,主動脈壓下降,在心舒末期動脈血壓的zui低值稱為舒張壓,也稱為低壓。血壓的測量,就是采用某種方法檢測和記錄血壓的收縮壓、舒張壓等數(shù)e
                                以及測量血壓的動態(tài)變化。血壓的數(shù)值一艙表示為壓力與大氣壓之差。血壓測量的壓力范圍為 0 ~
                                300mmHg。皿壓測量的頻串范圍通常為 0
                                ~20Hz。在常規(guī)的臨床檢查中,常常采用人工方式,使用由氣袖、壓力計和聽診5B等部分組成肋脈K
                                計,間接測量人體的收縮壓和舒張壓。與此同時在心血管功能檢查、病人監(jiān)護、生理實驗、以及體格檢查中,廣泛使用帶有各種血壓傳感器的電血壓計,盡管這種儀器十分的準確,技術(shù)十分成熟,但是仍存在諸如攜帶不方便,讀數(shù)困難,患者基本不能自測等弊病。德國的赫曼腕式血壓計,通過大規(guī)模集成電路,通過往腕帶中充氣加壓,再通過傳感器使得壓力信號轉(zhuǎn)化成為電信號,這樣不僅大大縮小了總體積,還配上一個脈搏傳感器,就可以在測量血壓的同時完成測量心跳,單位換算等諸多功能,十分方便,為患者自行診斷提供了可能。

                                電阻應(yīng)變片的工作原理
                                  金屬電阻應(yīng)變片的工作原理是吸附在基體材料上應(yīng)變電阻隨機械形變而產(chǎn)生阻值變化的現(xiàn)象,俗稱為電阻應(yīng)變效應(yīng)。金屬導體的電阻值可用下式表示:

                                  式中:ρ——金屬導體的電阻率(Ω。cm2/m )
                                  S ——導體的截面積(cm2 )
                                  L ——導體的長度(m )
                                  我們以金屬絲應(yīng)變電阻為例,當金屬絲受外力作用時,其長度和截面積都會發(fā)生變化,
                                從上式中可很容易看出,其電阻值即會發(fā)生改變,假如金屬絲受外力作用而伸長時,其長度
                                  增加,而截面積減少,電阻值便會增大。當金屬絲受外力作用而壓縮時,長度減小而截面增
                                  加,電阻值則會減小。只要測出加在電阻的變化(通常是測量電阻兩端的電壓),即可獲得:
