Sudden and progressive leakage detected
June 1st 2008 The LL series sensor
from ifm electronic
has four independent
switching outputs, and
continuous monitoring
of coolant or hydraulic
fluid levels. It indicates
vessel overfill with an
extra switchpoint,
which for safety reasons is
independent of the level
measurement, but ifm says the new
clever part is the leakage detection.
The two programmable outputs
of the leakage monitor
detect sudden and
progressive leakage
without additional
programming of the
controller.
The LT series sensor has
four outputs, two for level
monitoring and two more
which can be set to monitor the
temperature of the medium
between –10 and 100 °C. More articles from ifm electronic Limited: |
