A new type of piezoelectric accelerometer used for low frequency micro-vibration measurements is described. Its temprature transient sensitivity is very low, thus the environmental temperature transient variation causes very small effect only, therefore the lower limit of low frequency micro-vibration measurement can be reached down to a more small value.

The phase drift of the synthesizer, △φ, is 28.8° when the ambient temperature varies from 20℃ to 40℃. No change in output phase of the synthesizer was observed when the supply-voltage varied either from + 16V to + 19V or from +5V to +6V. The experiments show that it can operate continuously for more than one month without troubles, and can operate normally for ambient temperatures from 0℃ to 55℃.
