Resonance frequency for Sensorade sensors
How does Scanning laser-Doppler vibrometry work?
The laser-Doppler vibrometer is a precision optical transducer for determining the vibration velocity and displacement at a measurement position. It works by sensing the frequency shift of back scattered light from a moving surface. The object scatters or reflects light from the laser beam and the Doppler frequency shift is used to measure the component of velocity which lies along the axis of the laser beam.
Resonance frequency of absolute pressure sensors
The resonant frequency of the absolute pressure sensors reaches up to 2.7 MHz which is the highest resonant frequency on the market, as can be seen in figure 1.

Resonance frequency of differential pressure sensors
The resonant frequency of the differential pressure sensors reaches up to 310 KHz which is the highest resonant frequency on the market, as can be seen in figure 2.
