Intelligent PNP/NPN Switching Electronic Digital Level Switch with Local Display

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.

The level switch SLS takes the high integrated ARM industrial-grade MCU as the core. The SLS ensures fast-speed and precise level measurement and switch movement by carefully adjustment and combining high-precision AD switch and high stabile pressure sensor. The setup using the three big back-lighted buttons and the display on machine make it very easy for on-site parameters setting.

Features:

  • 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
