These self-contained Ultrasonic Sensors provide level
control of both liquid and bulk materials. This gives
the user a viable alternative to bubblers, floats, capacitance
probes, and pressure transmitters.
With sensing ranges of 30 and 40 feet respectively
many tanks are within reach. Their incorporation of
a microprocessor design makes it possible to achieve
signal conditioning. This gives the sensor the ability
to process the return ultrasonic echo and distinguish
between false targets and real targets.
With the incorporation of a microcontroller into the design
of the RPS-3000PVC and RPS-4000 many of the common problems
facing long range sensing applications have been overcome.
Software was then written to optimize the performance
characteristics of the sensors. The artificial intelligence
analyses and conditions the return ultrasonic echo. This
process filters out any false echoes and electrical noise.
An additional task that the microcontroller does is temperature
compensation. |
