Digital sensor for truck scales KELI QS-D

QS load cells are one of the most popular load cell models offered by Keli . It is used for railway and truck scales. This model of load cells has such advantages as explosion safety, impact resistance and high accuracy.
The KELI QS-D digital load cells have a built-in analog-to-digital converter (ADC) in their design. A digital weight signal is transmitted via the RS-485 interface, which can significantly increase the distance between the weighing platform and the weighing indicator (up to 1000m).
