【摘要】 针对大学物理实验中落球法测液体黏度实验存在的普遍问题,设计了基于多传感器系统的可控温式液体黏度测定仪.测定仪采用了集成霍尔开关传感器、温度传感器、超声波传感器等组成的多传感器系统,可以实现对透明液体和非透明液体黏度的测量.结合外部加热装置,还可以测量不同温度下的液体黏度.更多还原

【Abstract】 In view of the common problems in the experiment of measuring liquid viscosity by falling balls in university physics experiments,a temperature controlled liquid viscosity tester based on multi-sensor system was proposed.The instrument adopted a multi-sensor system composed of integrated hall switch sensor,temperature sensor and ultrasonic sensor,which could measure the viscosity of transparent liquid and non-transparent liquid.Combined with external heating device,liquid viscosity at different temperatures could be measured.更多还原
