Directional Microphone
MI-8100
MI-8100 is a shotgun type directional microphone which sharply catches the intended sound. This directional microphone is helpful for the removal of background noise in the simple sound source exploration and in abnormal sound detection. Flat frequency characteristic from 50 Hz to 20 kHz and sharp detection with high S/N ratio provide high sensitive detection of various sound coming from the specific direction. By combining the acoustic vibration monitor BL-1100, only the intended frequency or sound is focused and caught clearer.

Low Noise Prepolarized Microphone
378A04
The 378A04 is a matched system that is comprised of a high sensitivity microphone and a low noise preamplifier that contains a built-in filter that enables the free-field response to remain flat over a wide frequency range. The system requires a minimum of 4 mA and measures to 6.5 dBA (5.5 dBA typical) within a cost efficient, prepolarized (0V) design. PCB's model 378A04, the industry's first prepolarized low noise microphone and preamplifier system allows you to measure extremely low amplitudes. In the past this was only possible with externally polarized solutions. With a typical noise floor of 5.5dBA, this microphone system delivers all of the benefits commonly associated with prepolarized systems.

Microphones
MIC-01, MIC-02 and MIC-03 are low cost precision condenser electret microphones perfectly suited for laboratory and on-field acoustical measurements. They have identical performances but differ for their physical size; MIC-01 is preferable for fixed laboratory installations while MIC-02 is highly manageable due to its short length; MIC-03 is the best where space saving is a must. Their frequency response is individually tested against specifications and the sensitivity value is supplied. MIC-01 & MIC-02 & MIC-03 can be directly connected to your CLIO system's input.

ICP® Shock Accelerometers
Piezoelectric ICP® accelerometers afford a very high signal output (+/- 5 volts full scale) and the ease of two-wire electrical connectivity. Their inherent ruggedness enables them to be severely over ranged without damage. The addition of internal mechanical isolation minimizes the high frequency stress that would otherwise be encountered by their ceramic sensing elements. This mechanical isolation, coupled with an internal 2-pole electrical filter, built into the ICP® circuitry, tailors the overall accelerometer response to assure data quality to frequencies as high as 10 kHz. Depending on the specific model, accelerations in excess of 50 kg can be successfully measured. These modern designs, with their internal elastomeric isolation materials are verified through calibration to remain dynamically linear and are enabling piezoelectric accelerometers to operate in increasingly severe acceleration environments.

Cryogenic ICP® Accelerometers
Cryogenic ICP® accelerometers are specifically designed to operate at temperatures below the typical -65 ºF (-54 ºC) temperature limit of most voltage mode sensors. The use of specialized, built-in, cryogenic circuitry and quartz shear sensing technology promote survivability in demanding environments such as liquid nitrogen. Each sensor is hermetically sealed and individually tested to determine the thermal coefficient of sensitivity at -320 ºF (-196 ºC) ensuring reliable operation and accurate measurements. These sensors have been successfully used in the presence of liquid helium during structural testing of rocket boosters.
