Water Immersion Sensor

Features:
1) Operational principle: based on liquid conduction principle, use the
electrode to detect whether there is water, then transform to main
contact output by sensor
2) Functions and technical features:
a) Have the function of field warning indication to better measuring
and testing, be instructed with the diode, green light showing normal
while red light showing warning
b) Have two output states: normally open and normally close (normally
open as usual), contact capacity is DC 30V, 1A
c) Working power supply: DC 12V with the function of power protection
d) Power consumption: <0.4W
e) Isolated between input/output, power supply/output, the isolated
voltage less than 1,000V (leakage current 1mA, duration time 1 min)
f) Detecting sensitivity: 50k
