Z-SG / Z-SG2 are strain gauge load cell converters. The measurement, carried out with 4 or 6-wire technique, is available via ModBUS RTU serial protocol or analog output. The communication is configurable via DIP-switch or via software by connecting to the device with the Micro USB port on the front panel. Z-SG and Z-SG2 are galvanically isolated 3-way modules up to 1500 Vac. The load cell sensitivity varies from 1 to 64 mV/V. The instruments are configurable via DIP-switch and software (EASY SETUP). The strain gauge can be directly powered by the instrument. The load cell calibration can be managed through sample weight or software. The Z-SG2 version stands out for new functions (piece counter, automatic tare reset, threshold alarm, firmware upgradeable automatically) and new flexible measurement management modes (measurements available both in full and floating point, measurement stabilized by anti-noise filter, configurable resolution).
