Microphone Measures Explosive Blasts

A new high-intensity acoustic sensor has been designed for the measurement of dynamic pressure events, such as explosive blasts and high-level pressure pulses in the frequency range of 2 Hz to 18 KHz. The Model 973 microphone is suited for use in the most corrosive environments. Housed in a rugged stainless steel housing, it incorporates a hastelloy diaphragm. The MIL-style connector combined with a welded construction provides a hermetic seal. The sensor?s integral electronic buffer achieves a low impedance output when used with constant current sources of 2 to 10 mAdc. COLUMBIA RESEARCH LABORATORIES INC., Woodlyn, PA. (800) 813-8471.
