130F20 ICP® Electret Array Microphone
₹57,600.00
ICP® Array Microphone with integral preamplifier, BNC jack connector, TEDS
- Nominal Microphone Diameter: 1/4″
- Sensitivity: 45 mV/Pa
- Inherent Noise: 29 dB re 20 µPa
he PCB 130 series of Array Microphones are prepolarized, condenser microphones coupled with ICP sensor powered preamplifiers and are thus referred to as ICP microphones. This eliminates the need to purchase a separate preamplifier. The 130 series microphones provide an extremely cost-effective method for large channel count sound pressure measurements. Typical applications include sound pressure mapping, acoustic mode analysis, near-field acoustic holography, and vibro-acoustic testing, along with other applications.
