Infrasound Sensor

 

Compact broadband infrasound sensor based on a differential pressure transducer with a frequency range from 0.1-100 Hz. The sensor is the same type as also used for the debris flow/avalanche detection system MAMODIS. Two different analogue output ranges and four different sensitivities are available:

  Output range Sensitivity Full scale range
Typ 1: 0 - 3.3 V 0,156 mV/mPa ± 9,5 Pa
Typ 2: 0 - 5 V 0,131 mV/mPa ± 11,4 Pa
       
Typ 3: 0 - 3.3 V 0,077 mV/mPa ± 19,5 Pa
Typ 4: 0 - 5 V 0,066 mV/mPa ± 22,5 Pa

 

Power supply: 3.3-24 V

Power consumption: max. 0.03 W

Sensor cost: 990 €
