기능

• Can be powered by battery (24 VDC) even without AC power. In addition, the voltage between the electrodes is AC sine wave and there is no electric erosion, and stable detection is realized. • Self-holding of the output can be selected to be ON or OFF by self-holding by circuit processing. • Compatible with a wide range of liquids due to the variable sensitivity of the 0~100 kΩ operation resistance. • Eliminates contact wear by switching the relay contact chattering caused by conventional waviness to NPN output. • Complies with CE marking and is UL/CSA standard certified.
