AWA5661A型精密脈沖聲級(jí)計(jì)
AWA5661型精密脈沖聲級(jí)計(jì)是一種袖珍式、高精度的聲學(xué)測(cè)量?jī)x器,由于采用了先進(jìn)的數(shù)字檢波技術(shù),使得儀器的穩(wěn)定性、可靠性大大提高。本儀器具有動(dòng)態(tài)范圍大、操作簡(jiǎn)單、用途廣等特點(diǎn)。外殼采用ABS工程塑料,外形美觀,重量輕,便于攜帶;電池供電,功耗小;可外接濾波器進(jìn)行頻譜分析;RS232C數(shù)字輸出接口,可以和計(jì)算機(jī)聯(lián)機(jī)進(jìn)行遠(yuǎn)程遙控遙測(cè)。加上AWA5721或AWA5722濾波器可以進(jìn)行倍頻程或1/3倍頻程頻譜分析。廣泛用于各種機(jī)器、車輛、船舶、電器等工業(yè)噪聲測(cè)量和環(huán)境噪聲測(cè)量,適用于工業(yè)企業(yè)、環(huán)境保護(hù)、勞動(dòng)衛(wèi)生、教學(xué)、科研等域。本儀器目前有4個(gè)品種,AWA5661型,一般聲學(xué)測(cè)量用;AWA5661A型,屬于高性能型;AWA5661B型,主要用來測(cè)量低聲級(jí),如家用電器或微電機(jī)噪聲測(cè)量;AWA5661C型,用來測(cè)量高聲級(jí),如槍彈聲、爆炸聲、機(jī)械沖擊聲。 型號(hào) | AWA5661 | AWA5661A | AWA5661B | AWA5661C | 符合標(biāo)準(zhǔn) | GB/T3785 1型 IEC61672-1:2002 1級(jí) | 傳聲器類型(極化電壓) | Φ12.7mm自由場(chǎng),(0V) | Φ12.7mm自由場(chǎng),(0V) | Φ12.7mm自由場(chǎng),(0V) | Φ12.7mm自由場(chǎng),(28V) | 傳聲器靈敏度 | 40mV/Pa | 50mV/Pa | 50mV/Pa | 5mV/Pa | 頻率范圍(Hz) | 20~16000 | 10~20000 | 16~16000 | 16~12500 | 動(dòng)態(tài)范圍 | 27~140dBA 38~140dB | 25~140dBA 35~140dB | 20~135dBA 30~135dB | 50~160dBA 65~160dB | 頻率計(jì)權(quán) | A計(jì)權(quán)和L(線性)計(jì)權(quán) | 時(shí)間計(jì)權(quán) | F(快)、S(慢)、I(脈沖)、Peak (峰值,需計(jì)算機(jī)配合) | 檢波器特性 | 真有效值、峰值因數(shù)≥10 | 顯示器 | 3位半LCD,有欠壓指示、下限指示、過載指示 | 測(cè)量方式 | Lp,Lmax | 濾波器 | 可外接AWA5721型倍頻程濾波器或AWA5722型分?jǐn)?shù)倍頻程濾波器 | 輸出 | AC、RS232C至計(jì)算機(jī) | 電源 | 4xLR6或外接5V~9V電源 | 外形尺寸 | 220x2x2(mm) | 特點(diǎn) | 基本型 | 高性能 | 低聲級(jí)測(cè)量 | 高聲級(jí)測(cè)量 |
