Battery (24 VDC) allows use in locations without AC power supply. AC sine-wave voltage between electrodes enables stable detection with no electric corrosion.

• Outputs can be set to self-hold at ON or OFF using special circuits. 

• Adjustable sensitivity, with an operating resistance range of 0 to 100 kΩ, allows use for a wide variety of liquids. 

• Relay contact chattering conventionally caused by waves eliminated using open collector output, reducing contact wear.

• Meets CE marking and is a UL recognized component.
