A new conductivity-based sensor
from Gems detects the presence of
water in fuel and lubricating oil. The
WIF-1250 has no moving parts and
is an easy to install device that can be
used to prevent mechanical damage
as a result of lubricant property
degradation in a variety
of applications. It can be
mounted in any position.

It is a solid-state
solution that contains
integral, hightemperature-
rated
electronics that generate
an alternating voltage to a probe tip.

The presence of water completes the
circuit which, in turn, changes the
condition of the transistor output.

Output options vary and can be used
to actuate relays, LEDs etc, as well as
to interface with CMOS/TTL logic,
PLCs or microprocessors.
