Embedded scale SCT-1

Embedded scale SCT-1

SCT-1 is a stand-alone scale on a circuit board. It is intended to be embed in bigger and more complex devices and instruments. Mostly is used when dosing processes take place and weight measurement is needed. It is build of ADC, memory, serial interface and a small microcontroller. Power supply is 8-30V DC. Scale calibration, and the following weight measurement can be done only via serial interface RS-232/RS-485, using special software, developed by GINEERS. Data protocols are free downloadable at our web site.
