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.
Highlights:
- Modern design
- Operate from ICP® sensor power
- Low cost per channel
- Uses coaxial cables with BNC or 10-32 connections
- Interchangeable with ICP® style accelerometers and pressure sensors
- IEC 61094-4 WS2F compliant
- Designed to be used in an IEC 61672 Class 1 compliant system for sound level meter use
Applications:
- Environmental noise monitoring
- Automotive Noise, Vibration, Harshness (NVH) tests
- White goods products and component testing
- End of line testing
- Machinery monitoring
- Noise source location
- Aerospace cabin and engine noise reduction
- R&D product development
