Instruction Sheet
The Micromate's Linear Microphone automates the monitoring
of air overpressure and vibration monitoring in the same
unit, making it a cost effective and flexible device for these
applications.
The Linear Microphone is calibrated to the ISEE-2017 standard
with a frequency measuring range from 2 to 250 Hertz and an
amplitude range up to 500 Pascals (0.0725 psi, or 148 dB).
