The acceleration sensor is based on the strain gage technology.
The accelerometer sensor is characterized by small dimensions and a high resonance frequency.
The AS28 can be used, for static measurements from 0 Hz, for example for measuring building vibrations or vibrations on bridges and other constructions.
The temperature drift of the zero point noticed with a maximum of 0.2% / ° C, because semiconductor strain gages are used.
The input range of the measuring amplifier must be large enough. (when full range should be used) The output signal of the AS28 is approximately 10 mV / V at full measuring range. The measuring amplifier GSV-1, GSV-2 and GSV-3 are available with matching input sensitivities of ± 5, ± 10 and ± 20 mV / V.
The variant AS28e includes integrated electronics.
The output is ± 2.00 volt for all sensors AS28e at full range.
The zero point is set at 2.5 volt.
The output signal of variant AS28 without electronic is within the range of 6 .. 15 mV / V and it is reported individually on a separate test protocol.
