纵向振动换能器低温性能浅析

Analysis on Cryogenic Property of the Longitudinal Vibration Transducer

通过分析纵向振动换能器在低温条件下串联谐振频率和等效电阻参数变化情况以及产生的原因,提出防止在低温试验时损坏纵向振动换能器的措施。

By analyzing the series resonance frequency of the longitudinal vibration transducer under the condition of low tempera- ture and the parameter of the equivalent resistance, as well as the reasons, this paper put forward to the solution to protect the longitudinal vibration transducer, when working in low temperature environment.
