摘要
在原有的DH4615型音叉受迫振动与共振实验仪的基础上,设计了液体密度测量传感装置,通过实验数据测量、定标,对水、乙醇、汽油等液体通过测量谐振频率求得待测液体的密度,测量精度符合实验要求.
Based on the forced vibration and resonance equipment of DH4615, which is based on tuning fork, a liquid density measurement sensor was designed. After calibration, the resonance fre- quency of liquids such as water, alcohol and gasoline were measured, and the densities of these liquids were obtained. The measurement accuracy achieved the requirements.
