Sound Calibrator CA106/Electrostatic actuator EA002/Electrostatic Acturtor Power AS002

BSWA CA106 Sound Level Calibrator is a pocket-sized, battery operated sound source for quick and direct calibration of sound level meters and other sound measuring systems.

BSWA electrostatic actuator EA002 is especially designed for testing the frequency response of 1/2’’ microphones. It can be used to calibrate the sound level meters according to IEC61672-3 Standard

An 800V DC bias voltage is needed for driving electrostatic actuator. The AS002 is the electrostatic actuator power supply. It have built-in signal amplifier of 30 dB. It can take the signal directly from a data acquisition card.
