Clever level sensors
May 1st 2008 ifm electronic says its latest level
sensors do more than just check
levels.
The new LL series has four
independent switching outputs.
Continuous monitoring of, for
example, coolant or hydraulic fluid
levels in all kinds of vessels, is its
basic function. In addition, it will
indicate an overfill of the vessel
with an extra switchpoint, which for
safety reasons is completely
independent of the level
measurement.
The two programmable outputs
of the leakage monitor detect
sudden, as well as progressive,
leakage without additional
programming of the controller.
A second new sensor – the LT
series – has four outputs, two for
level monitoring and two more
which can be set to monitor the
temperature of the medium
anywhere between -10 and 100°C.
Integration of the level, overflow
and leakage monitoring function in
one unit, or combining level and
temperature, eliminates the need
for additional mounting, wiring and
software input. More articles from ifm electronic Limited: |
