Digital load cell conditioner DSC

Image DSC

DSC is a high speed and high precision digitizing load cell conditioner, along with linearization and temperature compensation.

It was the ability to convert standard strain gauge load cells into digital load cells. Available output formats include the RS232, RS485, ASCII, Modbus, CAN and MantraCAN (J1939).

The digital load cell converter has the option of being housed in a convenient IP65 enclosure, or for multiple load cell installations, refer to models DSJ1 display & junction box for a single digital load cell for 1 channel, and DSJ4 for 4 channel.
