Bruel & Kjaer UA-0023 UA-0033 Electrostatic Actuator kit, Complete, Excellent Condition, Free UPS Ground Shipping. The Bruel & Kjaer UA-0023 / UA-0033 Electrostatic Actuator kit includes the following: The UA-0023 (for 1” microphones) The UA-0033 (for ” microphones) Rosewood case Instruction card Connection cable. Actual item for sale is shown in the photos. Bruel & Kjaer UA-0033 & UA-0023 electrostatic actuators are designed to simulate the pressure response of condenser microphones. Oscillating electrostatic force is exerted in front of the microphone diaphragm, providing the consequent response of the microphone. By applying an oscillating electrostatic force - sweeping over a frequency range from 100 Hz to 200 kHz - the pressure response can be tested. B&K also makes adapters for measuring ” microphones using the UA-0033.  For a complete description of the electrostatic actuator theory and use, refer to the Bruel & Kjaer Microphone Handbook Volume 1, section 2.7, available from the bksv.com web site. The first paragraph is reproduced here: 2.7 Electrostatic Actuator Calibration 2.7.1 Introduction The calibration of microphones using an electrostatic actuator is a widely applied laboratory method for determination of frequency response characteristics of measurement microphones. The actuator produces an electrostatic force which simulates a sound pressure acting on the microphone diaphragm. In comparison with sound based methods, the actuator method has a great advantage. It provides a simpler means to produce a well-defined calibration pressure over a wide frequency range without the special facilities of an acoustics laboratory.
