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.
