Free-Field ICP Array Microphone Debuts

Designed for measuring sound pressure levels and frequencies in the audible range, the Model 130D22 is a combined ICP (Integrated Circuit Piezoelectric) free-field response pre-polarized array microphone and preamplifier. It can be used simultaneously with ICP accelerometers to simplify test setups. The device incorporates a SMB connector, which provides seamless transition for many data acquisition systems and software set-ups, and saves time when connecting multiple units, such as in a large channel array setup. When used with data acquisition systems that have 2-20 mA constant current supply, the system does not require additional power supplies. The unit has a sensitivity of 45 mV/Pa, uses standard low-cost coaxial cables, and also has optional TEDS capability. PCB PIEZOTRONICS, Depew, NY. (800) 828-8840
