The LTU-101A-R consists of a
sensor with dual tuning forks which
are vibrated at a high frequency.
As the tuning fork is progressively
covered by a liquid, a shift in
frequency occurs which activates
the relay output. The tuning fork
sensor is often used in conditions
where there may be frequent
composition changes in the liquid.
Factory calibration ensures
accuracy over a wide range of
liquids, including lubricating oils
and hydraulic fluids.
