Smart Stainless Steel Submersible Level Switch 4~20mA+PNP Switch
Output
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.
There is a large number of measurement ranges available from a
smallest measurement range of -0…1m H2O to 100mH2O. The zero point
can be adjusted by bottons. The connection elements are consist of
stainless steel and airway cable with a blowhole in the core.
Hence, it has high sealing perfromance and is well suited for a
large variety even of corrosive media. Supporting standard MODBUS,
the SLS makes it possible to remote data collection and parameters
setting, free customers from buying extra communication adapters.
For electrical connection the SLS has an M12x1 connector.
The SLS is compactly designed with housing with electrical
connection against process connection rotatable 330°, display
against housing turnable 180°, making it very easy for on-site
installation and monitoring.
