iXaL Series are accelerometers based on the Vibrating Beam Accelerometer (VBA) technology. The measurement uses the change in the resonance frequency of a vibrating beam under the inertial loading of a proof mass when subjected to acceleration.
The iXal A5 accelerometer includes 2 identical VIA* transducers in a push-pull configuration in order to reduce all common parasitic sensitivities e.g. temperature, pressure, aging. Two oscillator circuits continually maintain the 2 beams at their resonance frequencies and the opposite variations of the two frequencies directly provide the applied acceleration.
iXblue is able to supply on request the thermal model coefficients and the electronic board including the signal processing for three sensors.
* VIA = Vibrating Inertial Accelerometer based on French patent of ONERA
