SOUND LEVEL METER LUTRON SL-4013

Lutron Sl-4013 Sound Level Detector We the manufactures of SL-4013 model of LUTRON ensure that the sound level detector is an easy to operate device with provisions of setting the measuring mode to auto or manual. It has a computerized RS 232 interface which ensures that readings would not be measured incorrectly even if the level or loudness of the sound is too low or if its pitch is low. Product features: ? Possible to save read data in the device? s memory. ? In case system enlargement is required it can done with the AC output. ? It comes with external VR calibration.

VR is available for easy calibration. * Frequency weighting networks are designed to meet * Hold & Memory record ( max., min. ) IEC 61672 type 2. * Condenser microphone for high accuracy & stability. * Auto range & mamual range. * Peak Hold function for stored the maximum value. * A & C weighting networks are conformity to standards. * Warning indicator for over and under load. * Fast & Slow dynamic characteristic modes. * LCD display for low power consumption & clear read- * AC output for system expansion. out even in bright ambient light condition. * RS232 computer interface. * Used the durable, long-lasting components, including * Separete sound probe, easy for remote sound a strong light weight ABS-plastic housing case. measurement. * Compact and light weight plastic housing. SPECIFICATIONS Display 52 mm x 32 mm LCD ( Liquid Crystal Display) , 5 digits. Function dB ( A & C frequency weighting) , Time weighting( Fast, Slow) , Hold, Memory ( max. & min. ) , Peak hold, AC & RS232 output. Measurement Range 30 - 130 dB. Resolution 0.1 dB. Accuracy Frequency weighting meet IEC 61672 type 2, calibrating input signal on 94 dB( 31.5 Hz to 8 ( 23 5 ? ) kHz) , then the accuracy of A weighting is specified as following: 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, 2kHz - 2 dB, 4 kHz - 3 dB, 8 kHz - 5 dB. Characteristics of A & C. Frequency A weighting - The characteristic is simulated as " Human Ear Listing" response. Typical, if Weighting Network making the environmental sound level measurement, always select to A weighting. C weighting - The characteristic is near the " FLAT" response. Typical, it is suitable for checking the noise of machinery ( Q.C. check) & knowing the sound pressure level of the tested equipment. Frequency 31.5 Hz to 8, 000 Hz. Calibrator B & K ( Bruel & kjaer) , multi-fuction acoustic calibrator, model : 4226. Microphone Electric condenser microphone. Size of microphone 1/ 2 inch standard size. Range selector Auto range : 30 to 130 dB. Manual range : 3 range, 30 to 80 dB, 50 to 100 dB, 80 to 130 dB, 50 dB on each step, with over & under range indicating. Fast - t= 200 ms, Slow - t = 500 ms, Time Weighting * " Fast" range is simulated the human ear response time weighting. ( Fast & Slow) " Slow" range is easy to get the average values of vibration sound level. * The " Fast" & " Slow" time weighting range are designed to IEC 61672 type 2 requirement. Output Signal * AC output - AC 0.5 Vrms corresponding to each range step. Output impedance - 600 ohm. * RS232 output. Out terminal Terminal 1 : RS232 computer interface terminal. Terminal 2 : AC output terminal. * Terminal socket size : 3.5 mm dia. phone socket. Calibration VR Build in external calibration VR, easy to calibrate on 94 dB level by screw driver.
