PENKO Engineering recently completed the SGM800 Digitizer range. The
SGM800 Digitizer is a range of compact modules mounted on a DIN rail and that
seamlessly connect load cells and strain gauges using industrial process
control. Connecting weighing instruments directly to automation, is one of the
action points of Industry 4.0 and Smart Industry. Also weighing data are
important components of Big Data. For this, it is necessary that all the
weighing data collected in the field, also becomes available at a higher IT
level. To achieve this with as many companies as possible, PENKO Engineering
now offers the SGM800 Digitizer: a range of certified communications modules
for different protocols which can be used simultaneously for decentralized
control.
Protocols
What PENKO first has tackled, are various
protocols for industrial networks. PENKO solves this with six different
versions of the SGM Digitizer, As a standard all six versions communicate via
USB and RS485. The SGM820, includes Ethernet as an additional. Another model,
the SGM830, offers USB and RS485. The
SGM840 offers another commonly used combination: namely PROFIBUS with USB and
RS485. Finally the SGM850 communicates with RS232 / 422 plus the
aforementioned RS485 and USB. In situations where 0/4 - 20/24 mA is required,
the QMV Digitizer is optional equipped with a matching port. Thus
communication between existing load cells of weighing bridges, silos, tanks
and any other certified weighing signal is possible with virtually any
process automation.
Process Control
Except for
communication via various protocols with PLC or industrial PCs QMV, the
Digitizer is suitable as a mini controller for decentralized process control.
The software for process control is already available; as plug & play
application for a check weigher, a filling plant or a belt weigher. In this
way, the SGM Digitizer functions as a truly decentralized controller. PENKO
software also offers the possibility to configure the SGM Digitizer from a PC
via Internet. The user can use a remote connection to the SGM Digitizer with
G-Cal, in-house developed software by PENKO, for adjustment from every
location on earth. This software, calculates the settings according to the
gravity on the spot. Furthermore, the calibration is fully digital and
therefore quickly implemented. Pi Mach II, is a freely available PENKO
software for this purpose. The USB port, which is built-in as standard, can be
used for functions to make a back-up or to restore.
Precision
and Quality
Naturally the SGM Digitizer can be combined with the very
precise dosage controller of PENKO. At a rate of 1,600 samples per second,
24-bit internal resolution and 100,000 particles resolution, the data stream
is easily dealt with by the SGM Digitizer when it comes to control or
communication. The SGM Digitizer800 range is UL and CE certified, and OIML
certified by DELTA for weighing applications in accordance with the Dutch
Metrology Act and EU Directives 2014/31 / EU and 2014/32 / EU for
non-automatic and automatic weighing applications. It should come as no
surprise, therefore, that the instrument has already proven its worth not only
as an interface between the weighing sensors and overhead control, but also
as an independent controller for, amongst others, filling systems, check
weighers and belt weighers.
To meet quality requirements PENKO
recently audited all aspects that are important to ISO9001-2008. The results
of the audit was entirely positive so that a re-examination was not
necessary.
