Fiber optic microphone system with complete EMI/RFI immunity and passive, non-metallic sensor head. Designed for MRI scanner rooms, ATEX/IECEx hazardous areas (oil, gas, chemical, mining), high-voltage substations, nuclear facilities, security installations, and infrasound monitoring. 200 mV/Pa sensitivity, 3.15 Hz – 6 kHz frequency range, 114 dB dynamic range. Fiber transmission exceeding 2 km without amplification. Zero electrical energy at measurement point — intrinsically safe by design.
