Product Description

4-20mA Smart Hydraulic Water Level Switch

The level switch SLS 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 and the same device. In its standard configuration it has two switching outputs (PNP or NPN). In addition, there are configurations available with an analog output signal (0...20mA| 420 mA or 0...5V| 010 V) as well as with RS485 Link.
