Liquid level gauge is a gem
September 1st 2007 The ExOsense non-intrusive liquid
level gauge from Gems Sensors &
Controls measures the level of
fluid materials in plastic containers
from outside the vessel, eliminating
any chance of contamination.
The unit has two parts, a sensor
which is stuck to the outside of the
wall of the vessel at the required
height, and an electronic module
with mini USB connector.
The sensor incorporates
propriety transducer technology
employing piezoelectric material.
When piezoelectric material is
excited, it creates an acoustic
signal as a function of the natural
resonance of the material.
ExOsense sensors generate this
acoustic signal, direct it through
the bottle wall and sense the
reflected pulse.
The sensor has a small footprint,
and can be used with almost any
size and shape of vessel. More articles from Gems Sensors & Controls: |
