Page 2 INTRODUCTION The force from acceleration (vibration or shock) acting upon the mounting base, is The Dytran Model 3255C is a super light transferred to the seismic mass through the weight charge mode accelerometer with 15 pC/g crystals, stressing the crystals in shear mode and sensitivity.
Page 3 Using equation 2 and making the appropriate against the mounting surface. Check to see that substitutions and solving for the output voltage of the mating surfaces are meeting properly, i.e., that the amplifier in terms of input charge, amplifier they are meeting flush and that there is not an loop gain, and input and feedback capacitance we angle formed between the two surfaces indicating have:...

The accelerometer is usable above this trouble shooting advice. Often our service frequency but to use it above 5,000 Hz, it must be engineers may point out something which may calibrated at the specific frequencies of intended...
