Metra Mess- und Frequenztechnik  MMF

 

VM40 is a stand-alone system for typical building vibration measuring applications.

  • For structural vibration measurement to DIN 4150-3, BS 7385SN 640312a, Circulaire du 23/07/86 and many other standards like Federal Transit Administration (FTA) standard.
  • Includes high-sensitivity triaxial accelerometer, electronics for signal conditioning, monitoring, recording and battery
  • Safe user guidance
  • Measurement of main frequency by continuous FFT
  • Time and event triggered recording for up to 100 000 measurements
  • VM40B with SMS notification at alarm events
  • Robust aluminum enclosure for autonomous field application
