Abstract :
The frequency stability of a crystal sensor in liquid is influenced by a decrease in Q value. Also, the frequency stability is influenced by the water pressure, liquid temperature, and etc. this paper shows a new method of realizing a highly precise crystal sensor by using two crystal sensors for the purpose of solving the above mentioned problem. In conclusion, it has been verified that a crystal resonator having two pairs of electrodes on one AT-cut crystal blank can be used for sensors in liquid for various applications.
