R-SG3 is een compacte converter voor rekstrookbelastingcellen. Metingen, uitgevoerd met een 4- of 6-draadstechniek, zijn beschikbaar via ModBUS RTU of ModBUS TCP-IP protocollen. De gevoeligheid van de belastingcel varieert van 1 tot 64 mV/V. De module is een configureerbare webserver. Aangedreven door een 24-bits ADC, onderscheidt de R-SG3 zich door geavanceerde functies (stuksteller, automatische tarra-reset, drempelalarm, automatisch te upgraden firmware) en flexibel meetbeheer (metingen beschikbaar in zowel gehele als drijvende komma, meting kan worden gestabiliseerd door ruisfilter, configureerbare resolutie). De module ondersteunt ook Peer-To-Peer en ModBUS pass-through functies.
