Water Immersion Sensor

Specifications

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: 50kΩ
g) One sensor can take several electrodes (ten), equivalent to several
(ten) optical type sensors
h) External dimensions: 44 x 75 x 71mm
i) Mounting: 35mm rail or screw
3) Mode: water immersion sensor electrode (YDE-WDT-P)

The electrode of the water immersion sensor is composed of insulation base-plate
and thin stainless steel plate electrode, and thin stainless plate sticks on both
sides of the base plate. The dimension of the base plate is 3.94mm (D) x 54mm
(L) x 34mm (W).

It may be used to measure for different purposes according to the place where the
electrode is put. Putting the base plate on the ground with the plain side of the
electrode to test the humidity of the ground; while putting the base plate with
the outstanding side of the electrode to test the depth of the water on the ground.
The minimum depth of water detected is 1mm.
