LP10 series capacitive liquid level switch (plug-in type)Detailed product description：

Characteristics of LP10 series capacitive liquid level switch (plug-in type)

Reliable liquid level detection for conductive non layered liquids
☆ Provide a liquid level measurement or intrinsic safety type liquid level measurement
☆ PP or PTA acid resistant plastic shell with anti-corrosion properties
The probe and cable with a protection level of IP68 can be used for operations below the liquid level in tanks or troughs
☆ Relay or FET switch output can be conveniently interface with PLC, SCADA or alarm systems
☆ Optional normal on/off status
Technical Principles
The plug-in RF capacitor level switch determines the presence of a medium or air by detecting the conductivity of the medium, and a capacitor is formed between the level switch and the medium (liquid or air) in which it is located. When the probe tip is immersed in liquid, the capacitance changes greatly and the FET switch changes state.
