Pressure sensor raises the bar
Pressure sensor users remain in control with IO-Link interface
Baumer has picked up an Innovations Showcase award from Process Expo in the Dairy Prod- uct category for its PP20H pressure sensor. The award was won despite stiff competition from 17 finalists and Baumer puts its success down to the wide range of features ensuring out- standing performance in challenging hygienic applications. A condensate resistant silicon measuring cell providing a high de- gree of precision across the entire temperature range combined with an IO-Link interface are essential to the performance of the sensor. An IO-Link interface is the latest trend for these types of sensor, hence its incorporation into the PP20H. However, Baumer pushed the boundaries to ensure additional benefits, such as ad- ditional analogue output which, when combined with digital IO- Link interface, offers users even more flexibility. The result of these features means that during commissioning of
the sensor, users benefit from all the IO-Link advantages, ensuring sim- plified sensor parameterisation, whilst still allowing optimum process control via the 4-20mA analogue output. Furthermore, the IO-Link means users can call up additional process data such as the pressure of the mea- surement cell, or the temperatures of the pressure sensor and even the microchip in the central processing unit.
Access to this information allows for crucial investigations, such as whether an unusual
temperature rise has occurred in a container which may indicate a defect or faulty dosage of ingredients in a tank. As high temperatures may decrease the service life of the sensor or other system components this acts as an important early warning for the need for preventative maintenance, one of the advantages of Industry 4.0.
DC UPS for critical systems
The UPSI-2412 intelligent DC emergency power sup- ply from Bicker Elektronik, in combination with suit- able LiFePO4 or Supercap energy storage devices, reliably bridges power failures and brownouts so that the uninterruptible 24V DC power supply of process-relevant systems is guaranteed at all times. These include sensitive control and regula- tion systems, embedded IPCs, gateways, motors, actuators, sensors, monitoring and safety technol- ogy.
In this way, costly system downtimes and data loss can be effectively avoided. The DC UPS board UPSI-2412 is designed for flexible open-
frame system integration in customer-spe- cific applications. It enables individual emergency power supply methods for long-
term use in the fields of Industry 4.0, medical and laboratory technology, renewable energy, control and regulation technology, safety, vision and
inspection systems. In normal operation, the UPSI-2412 forwards the DC input
voltage directly to the output, charges the connected energy storage
device in parallel and monitors all relevant parameters, currents and voltages. In the event of a voltage drop or power failure, a MOSFET disconnects the input within a few microseconds and the connected load is supplied without interruption from the energy storage device and the UPSI-2412 provides a constantly regulated DC output voltage.

packs bigger punch test system Battery
The high powered Scienlab SL1700A Series battery pack test system is designed for high-voltage battery packs of up to 1,500V for automotive and industrial applications. In contrast to the vast laboratories with
multiple test channels needed to develop batteries, Keysight is addressing space and power limitations with the SL1700A Series battery pack tester that uses new high-voltage silicon carbide (SiC) technology to achieve higher
efficiency and energy recovery capabilities, which is crucial to reduce overall lab costs. It provides high power in a small footprint and is modular and
upgradable to address future power needs.“Our next generation battery pack test systems based on high voltage SiC technology, provide more power and higher voltages in less space, when compared to similar systems,” said Michael Schugt, managing technology director of Keysight’s Automotive & Energy Solutions group. “When combined with its energy efficiency, it allows users to design new batteries in their lab with greater flexibility.” A battery pack is a complex system involving high
voltages and currents, electrical and mechanical components, cooling system and a battery management system (BMS). All components require thorough testing to draw conclusions about the durability, range, efficiency and heating of the pack.
