1. General
Description
KM05 is a weighing transducer promoted by Keli Electric Manufacturing (Ningbo)
Co., Ltd. It applies for an industrial control fields (or other applications with analog
output). It combines weight display and analog signal together. Its signal
transaction of former part adopts high-precise A/D converter with 24 bits, and the
output of analog signal adopts D/A converter with 16 bits. Its shell is a small box
made from aluminum, easily to be inserted into its control cabinet.
