Array microphone reads SPLs for audible range
The 130D22 ICP free-field-response, prepolarized array microphone with preamplifier measures sound-pressure levels (SPLs) and frequencies in the audible range. It can be used with ICP accelerometers to simplify test setup for NVH studies, acoustic holography, sound-pressure mapping, and biomedical research.
The unit incorporates an SMB connector and, when used with data acquisition systems that have a 2 to 20-mA constant current supply, does not require additional power supplies. The unit has high 45-mV/Pa sensitivity, uses standard low-cost coaxial cables, and has optional TEDS capability. (Contact Andrea Mohn for pricing and availability.)
