超聲波泄漏檢測儀
用超音波檢測儀泄漏檢測系統掃瞄，可從耳機聽到泄漏聲或看到數位信號的變動。越接近泄漏點，越明顯。若現場環境吵雜，可用橡皮管縮小接收區和遮蔽拮抗超音波。另外超音波檢測儀泄漏檢測系統的頻率調整能力也使得背景噪音干擾減少。可檢查氣壓系統，測試電信公司所用的壓力電纜等。桶槽、管路、及軟管都可借加壓而檢測。以及真空系統，渦流排氣，柴油引擎燃料吸入系統，真空艙，船舶艙間，水密門，材料處理系統，壓力容器及管道的內外氣液泄漏等。
超聲波專注于工業領域泄(xie)漏(lou)檢(jian)(jian)測(ce)(ce)、氣(qi)密(mi)性(xing)檢(jian)(jian)測(ce)(ce)和預測(ce)(ce)性(xing)維(wei)護，產品和解決方案在(zai)鋼(gang)鐵及(ji)(ji)有色(se)金屬、煙草及(ji)(ji)食品飲(yin)料、汽車制造、化工及(ji)(ji)石油天然氣(qi)、礦山(shan)水泥、玻璃制造、電力及(ji)(ji)清潔(jie)系(xi)統、軍工、造紙及(ji)(ji)印刷、鐵路運輸(shu)、水處理、基礎(chu)設施(shi)、地鐵風機和大型空調系(xi)統、港口自動化等諸多行業得(de)到廣泛應用。

超聲波氣體泄漏(lou)的檢測原(yuan)理(li) 工作方式:
如果一(yi)個(ge)容器(qi)內或(huo)管道內充滿氣(qi)(qi)(qi)(qi)體(ti),當其(qi)內部(bu)壓(ya)強(qiang)大于外部(bu)壓(ya)強(qiang)時(shi),由于內外壓(ya)差較(jiao)大,一(yi)旦容器(qi)有(you)漏(lou)孔(kong),氣(qi)(qi)(qi)(qi)體(ti)就會(hui)(hui)從漏(lou)孔(kong)沖(chong)出(chu)。當漏(lou)孔(kong)尺(chi)寸較(jiao)小且(qie)雷諾數較(jiao)高時(shi),沖(chong)出(chu)氣(qi)(qi)(qi)(qi)體(ti)就會(hui)(hui)形(xing)成湍流(liu),湍流(liu)在漏(lou)孔(kong)附(fu)近(jin)會(hui)(hui)產(chan)生(sheng)一(yi)定頻(pin)(pin)率的(de)聲(sheng)(sheng)波(bo),聲(sheng)(sheng)波(bo)振動的(de)頻(pin)(pin)率與(yu)漏(lou)孔(kong)尺(chi)寸有(you)關,漏(lou)孔(kong)較(jiao)大時(shi)人(ren)(ren)耳(er)可(ke)聽(ting)到漏(lou)氣(qi)(qi)(qi)(qi)聲(sheng)(sheng),漏(lou)孔(kong)很小且(qie)聲(sheng)(sheng)波(bo)頻(pin)(pin)率大于20kHz時(shi),人(ren)(ren)耳(er)就聽(ting)不到了,但它(ta)們能在空氣(qi)(qi)(qi)(qi)中傳播,被(bei)稱作空載超(chao)(chao)聲(sheng)(sheng)波(bo)。超(chao)(chao)聲(sheng)(sheng)波(bo)是(shi)高頻(pin)(pin)短(duan)波(bo)信號,其(qi)強(qiang)度(du)隨著傳播距(ju)離的(de)增加而迅速衰減。超(chao)(chao)聲(sheng)(sheng)波(bo)具(ju)有(you)指向(xiang)性。利(li)用這(zhe)(zhe)個(ge)這(zhe)(zhe)個(ge)特征，即可(ke)判(pan)斷出(chu)正(zheng)確的(de)泄(xie)(xie)漏(lou)位置。 超(chao)(chao)聲(sheng)(sheng)波(bo)泄(xie)(xie)漏(lou)檢測(ce)儀器(qi)的(de)主機(ji)(暨接收(shou)端)可(ke)工作于被(bei)動態與(yu)主動態;當對輸(shu)氣(qi)(qi)(qi)(qi)管道進(jin)行實時(shi)檢查時(shi)，利(li)用它(ta)捕捉氣(qi)(qi)(qi)(qi)體(ti)泄(xie)(xie)漏(lou)時(shi)所(suo)產(chan)生(sheng)的(de)微小的(de)超(chao)(chao)聲(sheng)(sheng)波(bo)信號，即可(ke)判(pan)斷出(chu)正(zheng)確的(de)泄(xie)(xie)漏(lou)位置。這(zhe)(zhe)種工作方式被(bei)稱為被(bei)動態。
將超(chao)(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)泄(xie)(xie)漏(lou)(lou)檢測儀(yi)器的(de)(de)主(zhu)機(暨接(jie)收(shou)端)與超(chao)(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)信號(hao)發(fa)(fa)生(sheng)器配合使(shi)用時，可(ke)(ke)對被(bei)(bei)檢查物進行非實時檢查，即由超(chao)(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)信號(hao)發(fa)(fa)生(sheng)器 發(fa)(fa)射(she)一定頻率的(de)(de)超(chao)(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)信號(hao)，一旦發(fa)(fa)生(sheng)泄(xie)(xie)漏(lou)(lou)，超(chao)(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)將由漏(lou)(lou)孔漏(lou)(lou)出，用超(chao)(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)泄(xie)(xie)漏(lou)(lou)檢測儀(yi)器的(de)(de)主(zhu)機捕捉(zhuo)漏(lou)(lou)出的(de)(de)超(chao)(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)信號(hao)，即可(ke)(ke)判(pan)斷出正(zheng)確的(de)(de)泄(xie)(xie)漏(lou)(lou)位置。這種工作方(fang)(fang)式(shi)被(bei)(bei)稱為主(zhu)動(dong)態。與被(bei)(bei)動(dong)態工作方(fang)(fang)式(shi)相(xiang)比(bi)，主(zhu)動(dong)態工作方(fang)(fang)式(shi)不適合于實 時檢查，但是具有更高的(de)(de)可(ke)(ke)靠(kao)性
