Modern prepolarized microphones are designed with newer technology than traditional externally polarized microphones. Prepolarized microphones have many advantages over the externally polarized models. They use ICP® power circuitry invented for sensors by PCB®. By applying a polymer coating to the top of the backplate and embedding a charge on it, expensive 200V power supplies can be eliminated and 2-20 mA constant current supplies or signal conditioners can be used as the power source.
Prepolarized models excel in portable or high-humidity environments and offer interchangeability with other test equipment like accelerometers or piezoelectric pressure sensors. This enables the use of cost-effective coaxial cables with 10-32, SMB, or BNC connectors. Moreover, with a multiple-channel power supply, you can seamlessly conduct vibration and acoustic tests within the same setup, saving both time and money.
