What is the principle of water level switch?
What is the principle of water level switch? 1
Water level switch is also called water level pressure switch, water level sensor and water level controller. It uses the pressure generated by the high and low water levels in the washing bucket to control the on-off of the contact switch.
What is the principle of water level switch? 2
The water level switch is connected with the air storage chamber at the lower side of the bucket through a plastic hose. When the bucket is filled with water, with the increase of water level, the air in the air storage chamber is compressed, and the pressure is transmitted to the water level switch through the plastic hose.
What is the principle of water level switch 3?
With the gradual increase of air pressure, the diaphragm in the water level pressure switch is deformed, which pushes the moving contact to separate from the normally closed contact, and the normally closed contact is quickly disconnected from the male contact, and the normally open contact is closed with the male contact, thus sending a signal to the program controller that the water level has reached the set value or disconnecting the circuit connected with the electromagnetic coil of the water inlet valve to stop water inflow.
What is the principle of water level switch?
When the washing machine drains water, with the drop of water level in the bucket, the pressure in the air storage chamber and plastic hose gradually decreases. When the gas pressure is less than the elastic restoring force of the spring, the normally open contact and the male contact are quickly disconnected, and the normally closed contact and the male contact are closed, returning to the state to be detected.
What are the classifications of water level switches?
1, feed back the liquid level position signal, inform the duty room whether the water level in the center console reaches the specified water level, and control the related equipment (such as water pump) in linkage. The signal voltage is often 12V or 24V safe voltage.
2. Water level switches are divided into: capacitive water level switch, electronic water level switch, electrode water level switch, photoelectric water level switch, tuning fork water level switch, floating ball water level switch, etc. At present, the popular intelligent water level controller in the market is gradually replacing photoelectric and Hall switch by detecting the water level, installing the water level point set by users, automatically starting the pump at low water level, automatically stopping the pump at high water level, and preventing the pump from idling due to water shortage protection.
What's the price of the water level switch?
