Device for detecting viscosity or specific gravity of liquid

摘要

A device for detecting the viscosity or specific gravity of liquid includes a vibrator made of piezoelectric ceramics and capable of vibrating about its axis, a vibration transmission member, a detection terminal to be immersed in liquid, the viscosity or specific gravity of which is to be measured, and a vibration sensor provided on the vibration transmission member. The vibrator and detection terminal are connected to each other through the vibration transmission member. The detection terminal is vibrated within the liquid by the vibration of the vibrator transmitted through the vibration transmission member. The vibration sensor detects the vibration of the detection terminal immersed in the liquid.
