Infrasound sensor

Compact broadband infrasound sensor designed for monitoring of alpine mass movements

Compact broadband infrasound sensor based on a differential pressure  transducer with a frequency range from 0.1-100 Hz. The sensor is specially designed for monitoring alpine mass movements and is used for the debris flow/avalanche detection system MAMODIS. The output range fits also ideal for microcontroller inputs. Two different analogue output ranges and four different sensitivities are available: 

Type 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

*) Type 3 typically used for MAMODIS

Power supply:  3.3 - 24 V (depending on Type); Power consumption: max. 0.03 W
