HS-5660A/精密脈沖聲級計HS5660A
中文介紹
HS-5660A精密脈沖聲級計是一種便攜式聲學測量儀器,具有數(shù)字和表針雙顯示功能。它能夠分檔測量,其脈沖特性使其能夠精確測量沖擊聲和短持續(xù)時間的噪聲,例如槍炮聲、沖壓機聲、爆炸聲等。此外,該儀器還可與HS5721型1/1倍頻程濾波器或HS5731型1/3倍頻程濾波器配合,構成一個操作簡便的便攜式頻譜分析儀。
在技術參數(shù)方面,HS-5660A型精密脈沖聲級計的聲級測量范圍為30—138dB(A)、40—138dB(C)和45—138dB(線性)。其頻率范圍為10Hz~20kHz,頻率計權包括A、C及線性。檢波特性為真實有效值及峰值,時間計權有快(F)、慢(S)和脈沖(I)三種模式,并具備最大值保持功能。此外,儀器還設有過載指示,當信號超過滿度時會顯示+10±0.5dB。
HS-5660A采用4節(jié)1.5VLR20高能電池供電,通過專用AC附件,還可直接使用220V市電進行測量。儀器內(nèi)藏1000Hz正弦校正信號,可用于校準本機及配合使用的電平記錄儀的靈敏度。此外,它還具備交、直流輸出端,可與濾波器及記錄儀配合使用。
HS-5660A精密脈沖聲級計廣泛應用于環(huán)境噪聲、機器、車輛、電機等噪聲的測量與分析,也可用于建筑聲學、電聲等領域的測量。其便攜性、多功能性和高精度使其成為聲學測量領域的重要工具。
English Introduction
The HS-5660A Precision Impulse Sound Level Meter is a portable acoustic measuring instrument with both digital and analog needle display. It can measure in different ranges and is characterized by its ability to accurately measure impulse sounds and short-duration noises, such as those from firearms, stamping machines, and explosions. Additionally, the HS-5660A can be combined with the HS5721 1/1 octave band filter or the HS5731 1/3 octave band filter to form a portable spectrum analyzer that is easy to operate.
In terms of technical parameters, the HS-5660A has a sound level measurement range of 30—138dB (A), 40—138dB (C), and 45—138dB (linear). Its frequency range is 10Hz to 20kHz, with frequency weighting options of A, C, and linear. The instrument features true RMS and peak detection characteristics, and it has three time weighting modes: fast (F), slow (S), and impulse (I), along with a maximum value hold function. Moreover, it includes an overload indicator that shows +10±0.5dB when the signal exceeds the full scale.
The HS-5660A is powered by four 1.5V LR20 high-energy batteries, and with a dedicated AC accessory, it can also be directly powered by 220V mains electricity for measurement. The instrument has an internal 1000Hz sine calibration signal, which can be used to calibrate the sensitivity of the instrument itself and the level recorders used in conjunction. Furthermore, it has both AC and DC output terminals that can be used with filters and recorders.
The HS-5660A Precision Impulse Sound Level Meter is widely used for measuring and analyzing noise from environments, machinery, vehicles, motors, as well as for measurements in architectural acoustics and electroacoustics. Its portability, multifunctionality, and high precision make it an essential tool in the field of acoustic measurement.
