One of the thyristor-type liquid level automatic control circuits (fill-in type)a
Source: InternetPublisher:elleny Keywords: Thyristor BSP Updated: 2020/06/11
The circuit is shown in Figure 11-14. It uses a one-way thyristor and is a flooded liquid level automatic control circuit . Use electrodes as
detection elements for level control of water or other conductive liquids.
In the figure, Ri is the current limiting resistor, which limits the current flowing through the control electrode of the thyristor to avoid burning out the tube.
