61F-WLA/-GPN-V50
Operation
Operating Principle
When the two conductive cores of the Sensor Cable are contacted
by a liquid, a weak alternating current (as small as 3 mA max.) flows
across the cores. This current is amplified to operate a relay.
In practice, leakage will be detected if water drops are present be-
tween the core wire and the Electrode (F03-15 Sensor Cable) or de-
tecting section (F03-16 Sensor Cable). (Refer to the specifications
on page 70)
