随着乡镇居民生活的不断改善,许多居家都建有高位水箱自来水系统。目前大多采用电极式电子控制电路自动上水,但由于电极始终处于通电状态,电解作用使得电极探头容易锈蚀,故寿命短且影响系统工作。本文介绍的控制电路可克服上述缺点,具有电路简单、工作可靠、寿命长、成本低的特点。可广泛应用于水池水位的自动控制。 With the continuous improvement of the living standards of the townspeople, many households have built-in high water tank water system. At present, the electrode type electronic control circuit is used to automatically apply water to the water. However, since the electrode is always energized, the electrode probe is easily corroded by electrolysis, so the life span is short and the system operation is affected. This article describes the control circuit can overcome the above shortcomings, with a simple circuit, reliable, long life, low cost. Can be widely used in pool water level automatic control.
