OLED Electronic Digital Level Sensor Switch PNP + 4~20ma + Modbus
SLS Intelligent Level Switch is designed for level monitoring and measurement of liquid and oil media. It is applied to general industry such as tank, case, liquid cell and deep well. It is level switch, transmitter and display in one device. In its standard configuration it has optional two switching outputs (PNP or NPN), an analog output signal (0...20mA| 4…20 mA or 0...5V| 0…10 V) as well as with RS485 Link.
SLS level switch range is 0~100mH2O, with high measuring accuracy of 0.2%FS. It has normally open or normally closed, switch delay, switch point settable functions and so on. Thus our SLS is widely applied in various level / height monitoring and control.
