DAT
Digital/Analog Load Cell Transmitter
Digital / Analog Load Cell Transmitter Series based on last generation of A/D converters and microprocessors, obtaining a modern, compact and reliable design. It´s fully configurated and calibrated by front panel keyboard, avoids adjustment with potentiometers, reducing the difficulty of start-up, calibration and maintenance. It’s ideal for industrial installations with load cells.
