中文摘要:电容式液位测量系统是基于改变介电常数时,电容器的电容量变化的原理来测量液位的。利用电容式传感器,ADC0809,8031,2764,8155单片机和LED数码管等组成测量系统,对煤油的液位进行测量。它具有设定液位、显示当前液位和声光报警的功能。实验表明:该系统能对导电液体的液位测量,并具有结构简单、成本低、性能稳定等优点。
外文摘要:Capacitive system for liquid level measurement can measure the liquid level according to the principle which capacitance value is changed with the dielectric constant. The system which consists of capacitive sensor and single chip processor of 8031,ADC0809, 2764 and 8155, and light emitting diode(LED) is used to measure the liquid level of coal oil. It can enact the liquid level, show the present liquid level and give an alarm with voice and light. The experiment shows as follows. It can measure the liquid level of conductive liquid, and its structure is simple,its price is lower,its performance is stable.
