Infrasound microphone
07 December 2015
Expert in in vibration, acoustic, pressure, force and torque sensors, PCB Piezotronics has launched a new ½in (12mm) microphone and preamplifier system, model 378A07, designed for use in low frequency testing and ideal for studies ranging from wind turbines to natural events like tornadoes.
This free-field prepolarised microphone has a frequency range of 0.13Hz to 20kHz (±2dB) which meets the IEC 61094-4 standard for test and measurement microphones. This covers infrasound which is below the normal hearing range for adults.
PCB carries a full complement of prepolarised and externally polarised condenser microphones and preamplifiers. Prepolarised microphones use standard coaxial cables and are ICP compliant, allowing power supplies to be shared with other ICP compliant products such as accelerometers.
