MB3APP – TWO PRESSURE OUTPUTS VERSION
Categories:
Infrasound Sensors, Monitoring
Seismo Wave has developed a new version of the MB3a analog infrasound sensor in order to record high amplitude atmospheric events. The MB3aPP has two pressure outputs, which are respectively set at 2mV/Pa and 20mV/Pa.
This configuration greatly increases the dynamic range of the sensor by going from +/- 1,200 Pa to +/- 10,550 Pa.
Description
MB3aPP makes it possible to measure high intensity atmospheric events at a distance closer to the infrasound emission zone.
