WNK-SLS
4-20ma Output Smart Electronic Digital Level Switch Stainless Steel Submersible Level Switch
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.
