OLED Display Digital Level Switch Water Level Indicator For Hydraulic Fluid, Liquid Measurement

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.



  • Liquid and oil media level measurement
  • PNP switching, voltage and current outputs
  • Support MODBUS communication
  • Switching points settable
  • Switching can be set normally open / normally closed
  • Supporting Switching delay
  • Analog output span settable
  • High light switch indicating
  • OLED self-luminous display
  • Display turnable 180°
  • Housing with electrical connection against process connection rotatable 330°
  • Media density settable
