Description

e IRU 2000/3000 series
sensors use ultrasonic technology
to provide a non-contact method
of determining distance or level
measurements. is versatility
makes the IRU series ideal for a
variety of applications. e color,
translucency, dielectric constant,
specific gravity or viscosity of the
target does not affect an ultrasonic
sensor. Ultrasonic sensors
function extremely well in harsh
environments, are reliable, and
require little or no maintenance.

Operational Description

Ultrasonic sensing is very similar
to radar. e sensor transmits
ultrasonic sound waves. If the sound
waves meet a solid or reflective
object, such as a liquid, they are
reflected back and detected by
the sensor. e time of flight is
measured, and since the speed of
sound is a well-known variable,
the distance to the object can be
calculated.

Until recently, the many
variables in the speed of sound
created inaccurate readings. With
the advent of microprocessor
technology, these variables can
now be factored into the equation
and eliminated. One such variable
is ambient temperature. e
IRU series incorporates internal
temperature compensation to adjust
for changes in ambient temperature.
e IRU series also incorporates
programmable filtering options
to account for other variables,
such as waves on a liquid, or tank
irregularities. e distance to the
object is converted into an analog
output signal that is user adjustable.

Applications

e IRU series was designed for a
wide range of applications, including
presence/absence detection,
proximity detection, and level
control.
