PM-LD31A weight indicator is the younger brother of PM-LD01A model. In this model, in addition to 24-bit ADC and analog and digital filters, which achieves an extraordinary resolution of 1:100,000, a 16-bit DAC is used in the analog output section, which is designed with isolation. It performs the accuracy and speed of signal conversion with high accuracy and excellent speed.
The presence of digital input and relay output makes it possible to design the weighing system in different ways.
Also, if you don’t need analog output, PM-LD31 indicator model is recommended.
