Product Description

Lutron SL-4011 Sound Level Meter

Karya Mandiri Techindo has a wide range of Lutron products – search by type, or model, or filter by brand to find the one you are after. If you still can’t find it contact us..

Sound level meter with A and C weightings and SLOW FAST response CLASS 2 according to IEC 61672. This meter has the additional feature of signal integration over a programmable interval with calculation of SPL (Sound Pressure Level) and Leq (Equivalent continuous noise level). The sound logger is part of the Lutron SD series with logging at intervals from 1 second to 3600 seconds and data saved to SD card in EXCEL format, so further analysis can be readily undertaken

Specifications Lutron SL-4011 Sound Level Meter

Display18mm (0.7″) LCD (Liquid Crystal Display), 3 1/2 digits
FunctionsdB (A & C frequency weighted), time weighted (Fast, Slow), Max. hold down, AC & DC output
Measurement Range3 ranges, 30 to 130 dB, input signal only
Resolution0.1 dB
AccuracyThe frequency weighting complies with IEC 61672 type 2, calibrating the input signal at 94 dB(31.5 Hz to 8 kHz), then the accuracy of the A weighting is determined as follows:
31.5 Hz – ± 3 dB, 63 Hz – ± 2 dB, 125 Hz – ± 1.5 dB
250 Hz – ±1.5 dB, 500 Hz – ±1.5 dB, 1 kHz – ±1.5 dB
2 kHz – ± 2 dB, 4 kHz – ± 3 dB, 8 kHz – ± 5 dB
Frequency Weighting Network* Characteristics A & C.
* Weighting – Characteristics are simulated in response to “Human Ear Listing”. Usually, when measuring environmental noise levels, always select the A weighting.
* C-weighted – Characteristics approximate a “FLAT” response. Typical, suitable for checking engine noise (Q.C. check) & knowing the sound pressure level of the equipment under test.
Frequency31.5 Hz to 8,000 Hz
CalibratorB & K (Bruel & kjaer), multifunction acoustic calibrator, model: 4226
MicrophoneElectric condenser microphone
Microphone sizestandard 1/2 inch size
Range selector30 to 80 dB, 50 to 100 dB, 80 to 130 dB, 50 dB at each step, with over & under range indication
Time weighting (Fast & Slow)Fast – t= 200 ms, Slow – t = 500 ms,
* “Fast” range simulated human ear response time weight.
* The “slow” range is easy to get an average value of sound vibration level.
Calibration* Build in external calibration VR, easy to calibrate with external screw driver.
* Internal oscillation system, 1 KHz sine wave generator.
Output Signal* AC Output – AC 0.5 Vrms corresponding to each step of the range.
* DC output – 0.3 to 1.3 VDC DC, 10 mV per dB.
* Output impedance – 600 ohms.
Output terminals3.5 telephone output terminals are provided for connection with analyzers, level recorders, tape recorders
Operating Temperature0 to 50 (32 to 122). ℃ ℃℉ ℉
Operating HumidityLess than 80% RH
Power Supply006P DC 9V battery (heavy duty type)
Power ConsumptionApprox. DC 6mA
Dimensions255 x 70 x 28 mm (10.0×2.8×1.1 inches)
Weight280 g/0.62 lb (including battery)
