Process Control Sensors with Digital
Communication Interface
Digital communication
opens many opportunities-but only sensors that
reliably deliver precise
measured values offer real
added value by Baumer's
IO-Link. Well established
and appreciated by many
users, both pressure sensor PP20H and CombiLyz
AFI conductivity sensors excel by measuring performance and
IO-Link interface, but now they offer even more interesting
features such as simple and fast parameterization- even during operation. This way, secondary data like different process
data output simultaneously or diagnostic data only accessible this way can be communicated from sensor to controller
or even retrieved from the sensor memory if required. Dual
Channel enables analog as well as digital sensor operation
or both at the same time-this way, Baumer process sensors
such as conductivity sensor CombiLyz AFI and pressure sensor PP20H work both in conventional control topologies and
digital IO-Link control environments. In process automation,
the proven analog interface is helpful for sensor integration into existing control concepts. Nevertheless, in sensor
commissioning, IO-Link advantages such as easy and fast parameterization or access to secondary data are a valuable help.
For process control, parallel readout of conductivity or pressure value is enabled via 4... 20 mA analog output.
IO-Link provides access to valuable secondary data: process data including sensor temperature respectively process
temperature of PP20H. Such information allows for interesting conclusions, e.g., unusual temperature rise in containers
or pipes. Such data are basic for predictive maintenance. CombiLyz AFI conductivity sensor delivers information on media
concentration in addition to media conductivity. By doing
so, the medium in process and its concentration is precisely
identified. Pressure sensor PP20H delivers ambient pressure
information in addition to process pressure. Therefore, the
sensor can be deployed for both absolute and relative pressure
measurement.
With CombiLyz conductivity sensors and PP20H pressure
sensors now featuring this digital communication interface,
Baumer further adds on their portfolio of IO-Link process sensors. Solutions for flow and level detection using this digital
communication standard are also available.

Cameras Feature Fourth-Generation
Sensor
IDS has integrated the
high-performance, extremely high-resolution
sensor IMX541 from the
Pregius S series into the
versatile uEye SE camera
family. Thanks to its compact 1.1 " format, the 20.35
MP CMOS sensor is compatible with C-mount lenses. The industrial cameras feature
a practical USB3 Vision interface, deliver 20 fps and will be
available either as board-level models or with a robust metal
housing.
Pregius S-the fourth generation of extremely powerful
CMOS image sensors from Sony- makes BSI ( " Back Side Illuminated " ) technology available for the first time in global
shutter sensors. The benefits are smaller pixels (only 2.74 μm,
which allows a significantly higher pixel density), higher resolution and improved quantum efficiency and sensitivity. The
new camera models deliver outstanding image quality that
meets demanding machine vision applications such as surface
inspections, detailed image evaluation in medical technology
or use in the traffic sector.
The compact industrial cameras are also a sensible alternative to cameras with similar high-resolution, but large-format
sensors, for which F-mount lenses are usually required. With
the uEye SE models, C-mount lenses can be used-which
means considerable cost savings.
