NON-CONTACT POINT LEVEL SENSOR OVERCOMES MEDIA 'CHALLENGES'
Accurate,
efficient and reliable detection of fill levels is a key requirement
in many industrial flow and level sensing applications especially
when coupled with the growing demands of customer requirements.
For example, the trend toward increased automation adds additional
complexity in many processing and industrial applications, especially
in food, beverage, semi-conductor production, pharmaceutical,
printing and repro. Non-contact capacitive sensors are usually
the preferred option for these types of applications because
they are capable of detecting fill levels, without direct media
contact, even with the increasing variety and sensitivity of
the liquids often involved in these types of processes.
Capacitive sensing technology offers important advantages especially
on applications involving aggressive liquids, food or sensitive
pharmaceutical fluids used in closed containers, or where direct
contact with foreign particles must be avoided. However, in some
applications microfilms or residues will adhere to the inside
of the walls of tanks and vessels as the fill level drops. This
is where 'conventional' capacitive sensors reach their limits
of effectiveness because they are unable to reliably recognise
or differentiate whether the level measurement is still the medium
- or just the microfilms or residues.
Consequently the fluids handling system is in danger of running
dry, resulting in unwanted disruption and unplanned downtime.
Additionally conventional capacitive sensors being used in 'sensitive'
applications can be extremely sensitive to even the slightest
influence, for example just a touch of the tank or vessel may
result in switching errors.
Sensor specialist BAUMER continues to develop and expand its
range of innovative (and Award Winning) sensors and the challenges
noted above will not have any effect on their latest offering,
the new PL240 capacitive sensor. This compact yet robust sensor
can be attached outside plastic or glass tanks (even with a wall
thickness of up to 6mm). It can reliably detect point levels
of water-based media, such as cleaning fluids, milk or laboratory
liquids thanks to compensating adherence.
This compact point level sensor measures 40mm x 40mm and can
be quickly attached directly onto tanks, vessels or tubes using
adhesive tape, cable ties or screws and offers a very high performance
allowing for air gaps of up to 1mm between the tank and the sensor.
This means the sensor can be installed on a machine part when
using swap containers, especially where direct contact is sometimes
not possible, or is difficult to establish.
The PL240 sensor adds another user-friendly 'smart' fluid monitoring
option to the ever-expanding range being developed by Baumer.
