SVANTEK SV 33B – Class 1 Sound Calibrator

SV 33B Sound Calibrator is a class 1 sound calibrator produces an acoustic pressure of reference level 114 dB at frequency of 1 kHz. The SV 33B is suitable for calibration of Class 1 and Class 2 sound level meters and dosimeters with 1/2″ microphones.

SV 33B uses a built-in reference piezoresistive sensor for monitoring generated level, pressure and temperature sensors for measurements of atmospheric conditions and a microprocessor system controlling the operation of the calibrator. Sinusoidal waveform of 1 kHz frequency is digitally generated and feeds the loudspeaker. Sampled signal from the reference piezoresistive sensor indicates the level of currently generated signal in a feedback loop. On the basis of information about the level of the signal, actual values of pressure and temperature, microprocessor adjusts amplification of the loudspeaker signal in order to produce appropriate sound pressure level in the calibrator’s chamber.

SV 33B Class 1 Sound Calibrator provides a level 114 dB at frequency of 1 kHz. It is suitable for calibration of Class 1 and Class 2 sound level meters and dosimeters with 1/2 microphones.
