overview：

LSW5881SR liquid level switch is an intelligent liquid level controller integrating liquid level measurement, display and control. Output signal of the sensor is amplified, noise-reduced and adjusted by a highly integrated microprocessor to achieve accurate measurement, display and control of the switch output. All stainless steel shell, protection grade: IP65 for body and IP68 for probe, the meter head can rotate freely at 320°. The circuit design of this product has overvoltage, overcurrent and reverse polarity protection; it is suitable for complex electromagnetic environment; and it supports 24V DC or 220V AC power supply. Analog output (4mA~20mA DC) + 2 -way PNP, 2-way PNP, 2-way NPN or 1 way relay can be selected; support manual reset and measurement unit switching; OLED screen displays real-time liquid level value and switch status. It is widely used in water conservancy and hydropower, petroleum, chemical industry, metallurgy, transportation, electricity, machinery manufacturing and other industries.
