Electronics with Sensor
U Low-Cost Replacement
to Mechanical Float
The LVU-A710 Series compact
solid state liquid level switch is a
great replacement for mechanical
float-type liquid level devices. The
switch employs proven ultrasonic
technology and solid state integral
electronics in a small package.
The LVU-A710 Series provides
reliable operation in virtually any
liquid, regardless of viscosity. This
eliminates problems of stickiness
and failure rate due to finite
mechanical life inherent in the
mechanical float design. The
combination of fully epoxy-sealed
electronics and ultrasonic sensing
technology will provide years of
maintenance-free service.
